Formatting: You do some nice things with banners and columns, but you also have some paragraphs that need to be broken down, some spacing, and some need of bbcoding in other areas.
Content: Sections I found missing: Pros/Cons section, section exclusively about the jungling route, Section explaining core items, early/mid/late game section, role in teamfights.
Viability: I've yet to play Lee-Sin (I know, I'm missing out!), so I can only assume you know what you're doing with items and skill order.

Some notes:

• That paragraph in the "Why Play Lee Sin?" section isn't written very well. Your points are kind of all over the place. And you make some of the same points in the list right below it. I would just take the paragraph out and leave the list there.
• That paragraph for the Masteries section is confusing (because of grammar and paragraph structure). Try just using bullets for each separate idea.
• In several areas, you've misspelled safe guard / iron will causing a bbcode error (no space in safeguard).
• Your skill sequence/combos section needs to be sent through a grammar check.
• When you talk about jungling, you should explain why you go blue first instead of red.
• Your summoner spells section should be moved earlier in the guide, like between the masteries and skills seq/combo sections.
• You graphic for "Against Heavy AP Team" has some weird other graphic hiding in the layer beneath it, causing it to look like "AB" instead of "AP"
• You include an icon for IE as a possible item, but have no explanation for it. Actually, you don't explain several items. Make sure that you do.
• In the section where you list the neutral monsters, I think it'd make sense to list them in the following order: little camps, buff camps, dragon, baron.
• Why list those items in your jungle section? Shouldn't those be in your items section?

Overall, it's a nice looking guide, but there are some flaws beneath it all. I would focus on re-structuring it so that the order of things makes sense for the reader and then adding the missing content that I've mentioned above. Hope this helps, mate. Cheers.

Very well written and in-depth guide. Definitely goes into a lot of detail that isn't usually covered by many jungling guides. The effort you've put into this really shows - well done! +1

Reeeeeaaaally nice guide dude. +1

Excellent guide, REALLY like the way you did your match-ups section, it looks awesome! +1 vote from me!

Used this guide a sec ago in ranked :)
WON! :3

Wow, very inspiring design and format. I just would add the spell-graphics at the
"kill Sequencing/Combo"-section when you describe the Combos.
I really like the Counter-Junglers-chapter which is useful for every jungler. I don't know much about Lee but I can't find anything bad about your item-builds, runes or mastery-choice.

+1 :)

Your guide is just plain eye candy, it looks nice and I loved the layout. +voted it :D cheers! thanks for dropping by my guide

Good guide :D Nice description of items and skills. +1

Nice guide, pretty throughout and you point a lot of other viables.

Only 2 things I don't agree with. Legendary Armor is a bad mastery, 3 points for 5% armor and MR, it gives so ignorable amount. My point of view in detail below in the spoiler.



The other one is having both Black Cleaver and Last Whisper. In tearm of effectiveness Last Whisper is better than Black Cleaver, so the real question is do you need the CDR and the HP from Black Cleaver. Yea I if you get both their effects stack, but since armor reduction goes before any penetration, % penetration will go against lower armor, thus it will be less effective. The difference between only a Last Whisper and having both is not too much difference. I don't say it's totally ignorable difference, but I think +1 item slot worths more.

Since the Black Cleaver has been nerfed to 25% from 35% and made unique effect I only use it on champions who have armor reduction in their skills (ex Wukong, Renekton) or have natural flat penetration ( Olaf, is there any other?) and Darius becouse having close cap %ArP passively from your skill is way too OP to skip some more penetration.

Anyway I give it an up!

I agree good guide, the only thing i would add would be to specify the uses of the first three builds like build 3= Assassin build. Other than that its great to finally find a build that doesnt go support tank lee sin like most (Aegis Bulwark sightstone...). I would consider sightstone for the ward hopping though.
Good work as a whole.

Thanks for visiting my Review Shop!

Clearly, a LOT of effort was put into this guide. Definitely deserving of a +1.

Cheat sheet: 4.5/5. Overall, it's really well done. You included different builds for different situations, such as "Against heavy AP", etc. However, I strongly suggest you re-arrange the item builds a bit. What you have right now is good, but perhaps split it up, such as "starting items", "First item", "Second item(s)", "Items by mid-game", "Situational", etc. Put it all into the cheat sheet, in different sections. That's my idea.

Language: 5/5. The guide's in English, and is easy to understand. Your grammar is good, and the few mistakes I found does not interfere with comprehension.

Appeal: 4.8/5. The guide is aesthetically pleasing. You have a good amount of images and colour within the guide, and your images are detailed to the point where you can pretty much "learn" the champion just by looking at your pictures. (I mean, you included skills and typical item builds). However, I strongly suggest you remove the lore. That made it just a bit boring. Seriously, people read guides to learn their champion, not to learn their story. Also, that section did look like a big block of text. Remove that, and it'll be all good.

Viability: 9/10. I can't really make an accurate statement here, because I don't jungle very often, but your guide looks really good in theory. You've included details on item choices, skill builds, and counter jungling. I never expected to see a match-up list on a Jungler guide, but you have one. That's really good.

Overall: 4.7/5. It's obvious that you are experienced with the champion, and have put great effort into the making of this guide. There are a few typos here and there, but that does not interfere with guide comprehension. The biggest thing I would suggest is to re-arrange your cheat sheets to make it more "detailed" to account for situational picks, and remove the lore. +1.
