I really like Kayle as a champion, especially her ability to be nice and viable while building AP/AD/Hybrid/Offtank. But out of curiosity - are there any plans for her? Like Voice Over or something? Or gameplay update? Imo she doesn't really need one, but some new mechanics usually dont hurt.
MisterHealYoGirl2 votesI personally like that Kayle is one of those champions who can build basically anything and be pretty viable with it. Frozen Mallet/Liandry's/Nashor's? Seems legit. Nashor's/Rabadon's/Wit's End? Super cool. Thornmail/Trifrorce/BoRK? Follow your dreams, Kayle.

There's a ~99% chance changing Kayle's mechanics would hurt her.
Currently she's the only champion that can run top-lane, jungle, mid-lane, or support all at a competitively viable level. Unlike the handful of other champions that come close to doing so: Kayle only has 4 abilities rather than 7, and Kayle can do all 4 positions with essentially the same build, causing her to effectively be all 4 rolls (or all 5 - considering she's a pretty solid marksman-esque champion late) at once at any given time, where someone like Nidalee or Elise with similar flexibility generally has to build quite differently to pull off a different lane.
I don't see any changes to Kayle helping her out at all. Any mechanics changes would likely shoehorn her into a more specific set of lanning positions with a lot less flexibility, and her overwhelming pro ATM is that she's a jill of all trades.
Vianci1 votesYe that's probably right, they might accidentaly hurt her versatility and that's the last thing we'd like. Although i'd still see a VO since she has too few lines. Too bad there aren't many champions who can work like that, last being probably 
since he's good top/jungle/support so maybe Riot is more open to the idea than I think.
