Q remains the same E's heal is removed. no one cares about it anyways. Increase the speed duration W is now a 50% AS steroid along with it's current splash damage buff. No longer grants AA range because Kayle is now always ranged. R Is ANYTHING BUT A TARGETABLE TRYND ULT. That is nearly impossible to balance and needs to be removed. It's either too short and useless, or too long and too powerful.
Kayle's W is her heal and her E is her ranged splash ability. Also this topic isn't about changing what abilities actually do, so your post is kinda irrelevant.
"make any melee champ into a ranged champion"
Doing so would break a lot of melee champs so they would need a skill rework. I took the initiative to think of one for Kayle, since she's basically one, but not really.
