NOTE: i updated this compared to the original i had posted, because i found this more effective.
changes:
Malady early instead of sword of the divine.

So, ever since the new update with kayle i have been trying to find out how i want to play her, and i have been playing around with this build. it is rare that i have a bad score in a game with this build, no matter if my team wins or loses, so i think it's viable for mobafire now.

getting early malady is awesome because it stacks with kayles new passive, while giving that attack speed and extra magic damage all kayles love so much, and the extra early ability power boosts heals a bit as well. after that the early madreds buffs attack speed even more, which is ever so important on rightous fury, plus madreds (as far as i can see) progs with AOE plus the new (and amazing) passive that kayle has now. after that i follow up with phantom simply because more damage is not needed at that point in the game, so a speed increase is perfect. the black cleaver follows the really shred through everyone you meet, and a trinity force to make you allround insane plus giving you some late game survivability + boosting your heals a bit, if the situation comes to that.

As i have discovered these past few days, DPS kayle is a very effective teammate and her ulti still gives her the possibility of saving and supporting teammates, also because of CD reduc boots.

The runes i chose are simply because playing this build without early atk spd is stupid and it really gives the early edge needed. i mean for gods sake, it's lvl 1 berserker griefs!'

Anyway, i really hope you guys enjoy this build (it's my first) and do comment and so on if you feel like it :).
