Gave it a -1. I know you put effort into it, and a lot of it does make sense, but this type of Kayle stands no chance in a team fight or a 1v1. She just doesn't have enough sustain because there are no defensive items in this build. Also, I don't agree with some of the item choices.

I understand getting Hextech because you want to make a hybrid character, but there's just not enough AP in your build to take full advantage of the spell vamp.

Attack speed boots along with NT and Malady do not make sense to me. You're already getting +100% attack speed from these two items, so why not get Merc Treads? Or, why not get red of NT for Bloodrazor and get a defensive item like GA or Warmogs?

I'm not trying to rip you apart here, I'm just trying to give constructive criticism. In a team fight, this Kayle will only feed because she's just too squishy and does not have any methods of escape.

Thank you for noticing. I see yor point, and I know that an AD Kayle can be more effective. Personally I believe that if you want to win a teamfight, being there to give your team just a little more effective Divine Blessing along with the extra speed helps in the most tight situations. Another reason is that you want to do a good amount of damage, even if the enemy has either magic resistance or armor. The Malady along with runes to speed up the attacks, I think, weights it all up to something worth building.

Why would you ever build AP on Kayle... unless you're playing some type of support Kayle, which I'm sure this build is not geared towards. AP does so little towards Kayle's damage. Righteous Fury, your main damage dealer, would benefit so much more from Crit, AS, and AD. The only beneficial points from build AP is an increase in Reckoning and Divine Blessing. You're not going to be using those skills as much as RF.

not bad

looks pretty interesting. I'm looking forward for updates :)
