Hi. I never play Ranqued Solo/Duo as Lulu JG. I only play Normal Games for fun and Ranqued Flex with friends as a proof of concept of my strategies. As Ranqued Flex, although not really pushing for Elo, I did made great games with my Teams; I guess I were just around Silver Ranqued Flex. Mechanically (although probably not strategically) speaking, I already know from thousands of games as Lulu that I'm a match to at least Diamond players, including Monos.

If you really want to understand at least certain Winning Conditions for Lulu JG, you need to read this Chapter in the Guide:
⚖️ LULU JG — PROS & CONS

Also, this other Chapter may help in understanding what playing Lulu JG might mean:
🏫 LULU JG — COMMUNITY CONCERNS [ WIP ]

Currently, Lulu is a bit weak on all Roles on nearly all Elos... and this is very bad for Lulu JG of course. Nonetheless, the Compositional strategic aspects still apply (those are things that seldom change in LoL: Champions' Synergies).

"-Just... HOW?
HOW IS THIS GUIDE A THING???"

Hi again; so for the last questions…

I think one great thing about LoL, is that the game keeps changing.
So that even when I get tired of everything, including playing Lulu JG, then at some point there are huge updates… and then I'm usually intrigued to give it a try.

Although for sustaining a Guide big like this one it is indeed quite frustrating —it's like plenty of things we put in our Guide have an expiration date. For example, on this Preseason 2023's Patch 12.22, I was really considering if I should abandon this Guide and start a brand new one on Lulu JG. Eventually, I've opted for re-updating. This, because there are CERTAIN things that apparently don't change deeply. For example, this notion of:

⋄ Champion-Item Synergy (Trinity Force is an old Item; Lulu JG has been good with Trinity Force for a long time, even since before the Mythic Items system came to existence; and it is still good to this day); or even
⋄ Champion-Rune Synergy (Lulu JG with plenty of AS has always been a good thing to this day; but with the major Runes Rework years ago, Lulu JG with a Kiting Keystone has become really good at survivability and this can be a game-changer).

Because Riot chooses never to Re-Work Lulu Champion for real, her Kit is still quite effective on Jungle-Clear. So, anyone that has some basics at Jungle-Clearing can apply this consistently with Lulu JG's Kit —differently from most of the Enchanters. However, now we've got the Pets. So this opened up new possibilities; not only improving odds of any Non-Jungler Champions on the Jungler Role, but also allowing Lulu JG to not rely so much on Jungle-Clear Itemizations to be effective —since the Pets do a lot of the job.

It's because of LoL's dynamics in development, that we can probably get refreshing changes time to time, changing playing style, changing strategies or tactics, etc.. Changes that hopefully won't mean a total collapse of a Guide we've made or are maintaining —as some synergies persist, and some experience and knowledge that we collect are cumulative (this is essential in making a Guide like this I believe). Still, we are in need of making adjustments, more or less tweaks here and there on minor Patches probably; and some more important tweaks on deeper Meta changes.

A new interesting way I've found to keep Notes organized on my Guide; is that, whenever I add Notes now to some feature, I indicate the Patch. So that, even if I don't update that Notes again, at least people have a clue on when was that information created, whether it maintains functional or not.

I hope I was able to give proper answer to your questions.
¡Have fun! Cya

Hello, there; and thank you so much for your feedback.
Don't worry, I'm quite glad to discuss and answer to any questions about this niche that is Lulu JG; I hope you do not mind the huge reply though.

1) So, technically speaking, MOBAFire unfortunately doesn't get tools for copy-paste actions; I have recently asked them in the Forum for such kind of features. We can still copy-paste text-based data (like I usually do with certain repetitive Titles and specific Notes; and those conventional emojis are symbol characters edible for copy-pasting just as letters)… but that is far behind what would really be needed for optimal editing in this kind of Guide that relies on the presentation of multiple Builds.
Actually, not even the LoL Client, on its Item Collections for example, has got advanced copy-paste tools. There, we have got at least a clone/duplicate feature for an Item Collection, but we cannot copy-paste any particular portion (like an Item Group) from inside an Item Collection A and transfer it to an Item Collection B; so this is very frustrating in the LoL Client, even though I've already asked more than once Riot for developing new features relative to the Item Collections, but nothing has been accomplished so far.
Because MOBAFire is even more limited in this copy-paste regard, lots of handwork should be expected; but it's perfectly feasible. It's more or less like this: if you're already somewhat slightly familiar with MOBAFire's Guide-making, and you already possess well-organized amount information, it is not too complicated to 'recreate' those informations as a Guide on MOBAFire. It sure might take a few 'bursts of editing sessions' (much longer sessions especially if you intend on writing plenty of Chapters), but one can spread the editing time/sessions over an entire week or month in a fair way, despite no copy-pasting functionalities.
Note: I guess a 'burst of editing session' may be something around 30min to 2h.
Note2: For more iconic, visual information (like Items), I usually have the browser with at least 2 tabs: one with the editing page of my Guide, and another with my Guide but as being seen by a guest, so I can easily navigate anywhere on my entire Guide (from the 'guest' browser tab) as I edit one particular Section of one of my Builds. Naturally, on some other cases, I also need to be able to see visual information (such as Item Collections from LoL Client), whether because it's the first time I'm adding content to that Build on my Guide, whether because I have to make updates on it. Having the Client open simultaneously as the browser (if the computer can handle it) should be the easiest way); otherwise, taking multiple screenshots from a Client's Items Collection does the job (but it's just not optimal). More recently, I've found this kind of site, which allows to import an entire Items Collection file and visualize it on the web https://www.lol-item-sets-builder.com/import (it just did not get upgraded for new Items from Preseason 2023; but I hope it will soon).

2) I've decided to start this Lulu JG Guide in December 2021. The Guide was never 100% complete to be fair, and it is only more 'alive' today because I decided that I would prefer update it for Preseason 2023, instead of abandoning it and starting a brand new one from scratch. But, to answer more directly your question: I believe in order to have a good state of this Guide, that covered enough features (including Chapters), it took me probably from 2 to 3 months. But it often worked progressively, because I've started then with 0 experience in making Guides on MOBAFire; so I had to learn MOBAFire Guide-making as I was learning the best ways to present the content that I felt was required (researching how certain specific users presented their cool Guides helped me a lot with ideas and in conceiving different approaches and features that MOBAFire possesses). Basically, as I kept playing LoL (and Lulu JG), I kept gathering additional, relevant data; and at some point, like once or twice every month maybe, I've picked a day or two in which I would dedicate a few hours to make updates to the Guide on MOBAFire. Sometimes, I felt like my Guide was lacking certain crucial information, or was confusing in certain aspects; so at some point I'd tell myself I'd need to address that issue one day. For example, I still have to explain ALL the secondary Items for Lulu JG, and even though this is not a sooo big WIP (it mostly involves lots of Notes writing and thinking; so it's not that hard to implement), but it's certainly my major 'debt' to this day, and I'll certainly be fixing it at some point eventually.

3) 2015 is when I've started started playing LoL; I mostly played on the Support Role with Enchanters. But playing Lulu was different for me though: I started to understand the Champion's versatility as some sort of 'pseudo-duelist'. I don't remember why nor how, but I've intuitively started to play Lulu JG with a clear intent: making Full AS Build. These were the Metas with the 4 stone enchantments choices for the Jungler's Items; and "Devourer" was the one with AS… and infinite scaling On-Hit Damage. I've only heard about the term "Machine-Gun Lulu" much later; but it doesn't necessarily mean that I didn't get Lulu Build references from other players —I just don't remember; for me, it just felt natural. I played this way mostly for fun, on Normal Games. Those were the days where the only real complicated matches Lulu JG (on this kind of Build) could have would be Shyvanna and Warwick. As the years passed and I kept playing Lulu SUP and Lulu JG alternatively, becoming eventually a Mono Lulu, I kept gaining this intuitive, chaotic "Machine-Gun Lulu" and On-Hit experience and many of the Champion's "limits". Because Lulu is so squishy, at some point (I'm not sure when exactly) I've started to develop this notion of a "Hybrid Lulu" on the Jungler Role; where, in order to be more Supportive to the allied Team, Lulu JG should Itemize for a combination of Stats that would improve the Champion's abilities to cause as much Damage and CC as possible, as much as to Survive way more more than it should according to usual expectations. This Building strategy allows Lulu to play more aggressively and take more risks beyond early game; most important of all: in principle, should still be able to solo most squishies if is able to approach them somehow.
But LoL is an always changing game, ¿right? Something really big happened I guess in the end of 2020 when came Preseason 2021 (¡the Mythic Items system!). I haven't been playing for a long while by that time… but when I cam back by the second half of that year of 2021, I realized (nearly) EVERYTHING that I knew about Lulu JG was no longer there, and apparently Lulu JG was no longer Feasible anymore… I tried and tried… but then I nearly gave up: it so seemed it was the end and I was about to 'retire'. But this was the turning point for me; as I started to learn more about how the Mythic Items worked (and how each of them would interact on Lulu Champion), along with more synergetic Rune Pages, this helped me re-assessing the potentialities of Lulu JG as something more Utilitarian than I ever imagined on the past. This was also followed by my personal growth in understanding how the Jungle strategies worked at that time (something I really never cared much about in the past); so I studied analysis for Jungler players, and tried to converge those concepts with what I knew about being an 'oldschool' Lulu JG, but willing to adapt to this new reality, in this 'quest' of 'making Lulu JG as Feasible as possible'. It's from those mixed up events that I've realized I had some ideas to share and that a MOBAFire Guide on Lulu JG (on my "Hybrid" or "Versatile" Lulu JG concept) would be interesting. At that point, I was also more curious than ever about other Guides or ideas regarding Lulu JG (or any other original Build on Lulu for other Roles), so I did learn very special, powerful Builds thanks to other Lulu Main/Mono players (I remember very well I was pretty skeptical about Press The Attack and Galeforce; but now I know how powerful those are, combined or not; but I probably wouldn't have done that alone).
Then, of course, the main reason I was able to gather all these content, is because of my passion being a Mono Lulu and a Main Lulu JG. So I just keep experimenting stuff and fighting bizarre Match Ups, because I'm often trying to tackle something new that could perhaps be a game-changer, even though I should rather just focus on what I already know should be the most optimal and synergetic Builds for Lulu JG. It requires consistent 'iterations', playing regularly or not. And since I really don't how how to play 3/4 of the Champions in LoL, I have my playing time mostly dedicated to Lulu JG (I can't even play Lulu SUP anymore) and a few Enchater SUPs. I particularly admire those players that are so Versatile they can play well with nearly all the Champs in the game, and play in whatever Role. For me, most of my Versatility is just this: "Lulu JG". "¿What can Lulu JG do in this game to improve changes of Victory?" This is the question I pose myself everytime on the Champions' Selection (even when I'm testing some Builds/Itemizations).

4) To be continued…

¡Yeas! It can be quite funny, especially when the adaptive build (Runes+Items) we make up for a particular game works more effectively than not, and when our team is ready to play with a so unexpected Jungler champion. I wish you good luck, I'd be glad to hear about your Lulu JG stories. ¡Cheers!
PS: By the end of this week, I'm planning to make an important update, because I've been able to gather more data through some recent Lulu JG games.

Thank you for the nice feedback!
I didn't know much about Diana's itemization intricacies. But it strikes me to read her passive and see that she may benefit consistently from APSD as well.
I particularly like Lulu JG's idea because, in that kind of lonely and rotating role, she is often able to build or itemize in different ways that can be great to the team, but which might not work well if she were a Laner; sometimes, this can work for Lulu SUP too, commonly with lower Level and Gold though.

Hi, there. Thank you for your feedback.
Sure, I can send you the notes, but before, please, ¿can you confirm that such unreadable notes are being unreadable because their popup text box is vertically too large to the screen? Because if it so, I've already noticed (so annoying issue) and have been trying to fix it, rewriting smaller notes and creating chapters for the older big ones.

Edited: I've updated all of the text box notes. ¿Is the issue fixed? Thanks.

¡Thank you! this means a lot to me.
I'm glad a fay soulmate found it relevant somehow.
As this is my first MOBAFIRE guide, I'm sorry if the presentation and content are still in need of improvements and polishing; but the good part is that I'm working on this. Also, since I am playing regularly Lulu JG, I'm constantly collecting information (for exemple, about itemization variations and Jungle matchups) that will make this guide a bit more complete. ¡Cheers!
