How does this review work:I'll be going into four 'main' topics: Cheatsheet, Content, Presentation and What can be Improved?. All of these topics alone can turn a great guide into an even better one. Just knowing the ins and outs of your champion alone won't be enough if you're not able to properly convey said information. The end goal is always to make it easier for the readers that come to your guide of course.
I'll specify these main categories with purple text within this review, as well as some subcategories which will mostly depend on your guide chapters and for that I'll use the following rating system:

Cheatsheet

>Runes: Adequate

Conqueror + Resolve is the current standard option for Irelia, why? Your notes do not explain why this page is used. It is true that further down in your guide you will likely explain the reasoning behind this choice but a cheatsheet is exactly what it says "a cheatsheet" a page made to give the reader as much compact and to the point information as they can get as fast as possible (ideally even before games) if they wanted to continue to read through the guide after the game and enjoyed it, they will. I believe you should explain the reasoning as to why this page is the most popular one currently.

Again the differences between the Conqueror and the Tempo builds is nonexistant, aside from the keystone itself. The notes do not explain the reason to go these pages and it's quite unclear for the reader. Lethal Tempo offers 1v1 potential while Conqueror is the absolute standard, why? What makes tempo stronger than the standard option for the champion and when would it be more optimal to pick that 1v1 page, what specific matchup (or even certain team compositions) would justify this page over the standard Conqueror page?

Midlane Experiments is just fine, even though I'd argue calling it "experiments" is a bad title - if it's popular for midlane on her it's not very experimental - stat sites are currently showing inspiration to be more used rather than domination for midlane Irelia, which one can be used better?

Unsure why the 2nd best standard option for Irelia is featured last out of the 4 pages. I am also confused as to why you do explain the reasoning behind this rune page in your notes, but not the others?

>Summoner Spells: Exquisite

Note: Exhaust / Barrier quite questionable. Especially even more for toplane where they're entirely irrelevant. Ignite + Teleport has seen more uses here. For midlane I am not entirely opposed to the Exhaust but the Barrier option is still a no-go.

>Items: Adequate

First Back: No notes to explain the default option - Long Sword + Refillable Potion, why is it the default option? Why is it an option?

Boots: Don't like the "further details below". Again, readers want info quick, not more scrolling. I believe rearranging the sentence to say "Depending on the situation. Mercury's for heavy AP or heavy CC and Steelcaps for heavy AD or a lot of auto attacking champions (e.g. Yasuo). When to buy them is up to you although they're usually bought after bork." accomplishes the same goal.

Core Items: Doesn't feature Ravenous Hydra, it seems to be quite strong on Irelia at the moment. I enjoy your notes a lot more here.

Mythics: Trinity + Stridebreaker seem quite useless this patch and generally there are better mythics to pick from that are also shown to be more picked. Besides if Jak'Sho is the current best mythic item on her currently, then the other mythic options don't really matter at all. Why change when Shoe be best? If divine sunderer is a mediocre item for her, the simple answer would be - don't built it. Why? well it's mediocre, there are better options to pick from, otherwise it would not be mediocre.

Useful Items: Randuins + Frozen are explained, not death's dance though. Why is death's dance a good option to build against AD? I think you can expand this section to include all possible items to build on Irelia and what they can accomplish for her. For example, you talk about Sterak's in your against AP notes, no explanation of sterak's anywhere in this section though - could fit into against AD. No mentions of ravenous hydra whatsoever, even though it is included for the build examples. Warden's Mail could simply be removed and explained in the notes for Frozen Heart / Randuin's Omen, the main reason you'd want to build it would be for Randuin's due to the negation of basic attacks - this can be explained in those notes instead. Can include the upgraded version of the QSS right next to the item - so you'd have QSS and on the right of it the upgraded version, your choices are between Mercurial Scimitar and Silvermere Dawn, which one is more useful?

>Ability Order: Exquisite

>Threats & Synergies: Exquisite

Note: Could extend your explanations for the synergies but overall they're fine.

Content

>About Me: Exquisite

Note: Could also center the image and explanation, so for example -

>Why Irelia: Exquisite

>Pros and Cons: Exquisite

>Runes: Adequate

Here you talk about the different keystones and when and why you pick them, this is great! Why was this not in the cheatsheet notes?

General advice for most of all the sub runes is to scrap all the descriptions of the ones that aren't worth it. If Overheal is horrible, remove it. If Presence of Mind isn't needed and instead you should focus on managing your mana and abilities, why even include it? Just scrap them both and just talk about the rune that is worth it - Triumph. If you don't need Cut Down why talk about it? Never use Overgrowth on this champion - but let's include it. I like the side icons that showcase every possible rune, but you've already highlighted the good ones and good keystones by making the icon bigger and giving them a yellow/green border. This is awesome! But not all of them need to be talked about if they aren't going to be useful.

>Tips and Combos: Exquisite

Note: Can again make use of the center tags for the clips, can make them show a bit more neatly.

>Early game: Exquisite

>How and when to freeze: Exquisite

>Mid game: Exquisite

>Teamfights: Exquisite

>Conclusion: Exquisite

Presentation

> Execution: Will need a lot of work

If there's one thing I'd say about your guide that I feel like you can improve on, it'll definitely be this. I know very well that making use of BBCode can be a very tedious task in of itself to make use of or just to be able to get familiar with in general, but when it comes to presentation, making use of some code can really make your guide become more alive, so to say. You've already got a very good start on some code and that is already lovely.

Here are a few coding guides that we already have on the site that could help you if you'd be willing to dedicate some of your time to learning it (or if you just want some quick templates to make your guide look a bit more tidy):

- Making A Guide (has lots of free to use templates)
- BBCode Guide (the actual bbcode guide if you'd want to know how different codes work)
- A Table Coding Guide (talks about the bbcode that is called tables)
- Responsive Columns (talks about responsive columns; mainly for mobile side coding)

>Theme of guide (color scheme): Will need a lot of work

I feel like having a bit of a color theme would go a long way for any guide. This will be especially clear if you were to incorporate some BBCode for your sections. When I say the word 'color theme' I mean using colors that best represents the champion & guide you're trying to make. For example, the guide is about Irelia, which means that a good color theme to have could be e.g. Pink or Light Blue, resembling her classical skin. If you were to use a skin, using combinations from those skins could also be a nice addition and so forth.

What can be Improved?

If there is two things your guide can improve on the most, it's definitely to incorporate some BBCode to make the guide more alive and fresh, as well as talking more about gameplay options you have on Irelia and how to play those. Here are a few examples of some topics:

- How to make use of vision (Pretty important for a toplaner)
- How to track the jungler
- How to transfer your lead into a potential win
- How to play the game when falling behind (especially on a champion like Irelia)
- When and how to Roam (If needed)
- What to do during the late stages of the game. There is more than just teamfighting/splitpushing - e.g. objectives.
- Wave management (There exists more topics other than just Freezing. Slowpushing and Fastpushing waves is another very common tool utilized to manipulate waves in your favor).

These topics can all be useful topics to explain, and of course there can be multiple more that you can talk about when it comes to toplane as a role and Irelia as a champion, but I feel like these are some of the more important ones.

Overall Thoughts

This is a very well made guide, but can definitely use some improvements in various places. It's a wonderful start that I'm sure can go a very long way. I hope that this review will be of help to you and I wish you good luck. :)
