Kayle can outlane nearly everyone on mid.

Ofcourse, it all depends on player's skill and all but,
it's kinda funny to outlane such lane bullies like kassadin or vladimir with little kayle ^^

Really good guide!I've really only seen Kayle up top and that has only been recently, so I may try it since she's so cheap anyways. The one thing I'm going to suggest is the use of pictures and video's if your able. I'm sure people want to see how this Zhonya's Hourglass trick of yours works before trying it for themselves, so why not show yourself in action doing so? Overall, good guide, though brief, and it makes me wanna try her out.

Hey Trevor, I'm Trevor :P

Regarding your guide, I really like your effective use of BBCode, it really makes it stand out from other guides. The one thing I'd like is some more in-game pictures, such as a warding map for support Kayle, since warding is an extremely important job of supports. I'm sure if you asked, someone would let you borrow theirs if you credit them, but you can make the explanation your own.

As for the builds themselves, I really like builds 1, 2, and 4. The only changes I'd suggest is to start Prospector's Blade and Boots, since mobility is extremely important in the Dominion metagame. You don't lose very much at all by substituting that Dagger early game. Also, in dominion, you level so fast that the less flat runes you have the better :) I feel that taking two or three sets of scaling runes and one set of flats to help you in that initial top teamfight is sufficient.

Have you ever tried Kayle in the bot lane in dominion? She's really great at pushing and sustaining herself with Righteous Fury and Divine Blessing. And with the speed you reach level 6, you can often take the enemy turret early in the game, forcing the enemy team to support their bot by relocating a second player, giving your team a huge advantage, even if they had been losing before. Whether you choose to go bot lane or not, I would atleast put one point in Divine Blessing by level four. The healing isn't useful up top, but movement speed is, which is why I might also recommend the summoner spell Ghost as an alternative to what you have. Lastly, you can not buy Madred's Bloodrazor in dominion. I think you mean Kitae's Bloodrazor.

I don't understand Zhonya's Hourglass in build 3. I read your rationale behind it, but on an AD carry you're wasting a lot of damage potential by using it. That's the reason you have Righteous Fury and Intervention. You can do damage from far away and make yourself invulnerable if they get too close for comfort. I prefer Banshee's Veil on a carry to block any negative CC like a stun or snare that would've been my undoing.

I'd also like to ask that you move the section about how to play each variant of Kayle to after the explanations of things you set up pre-game, such as masteries, runes, etc. The guide is more "fluid" this way for lack of a better word.

After all that criticism, you'd think I'd downvote, but I'm always this way on guides I review. And you sir, are very deserving of this upvote.

+1

EDIT: Last thing :P I think you should include the exact order in which you build items in the area at the top. Not everyone takes time to read a full guide unfortunately, so they won't know what items to start with on support Kayle for instance.
