New kayle feels like a afk simulator
You have no ability to trade in a solo lane because your autos hit like a twig early on. Your q can secure a little bit of farm while you get the lane frozen on you and get zoned off. Your e lasts one auto so you can't get much off of it for its cost early on. Feels really bad to a lot of matchups so far as most characters are better early on.
Once you hit 11 the game becomes very fun and kayle feels much more fluid. Hitting 16 feels honestly broken, peaked at around 200 true damage on autos so far without counting all the other sources. Game doesn't even feel fair at 16 but extremely fun.
Maybe decrease q mana cost early on so if you're gonna afk get shit on you can secure farm. I just ended up playing her jg and farming to 11 and then turning the game around my last match.

. I think she'll be fine...in the jungle. Anywhere else shes's going to have a ton of horrible matchups.
