Kayle's E duration needs to be lower at early levels
i want to make a point of saying that overall i think kayle is balanced
i also want to say this: nothing feels worse than laning against kayle as a melee top and having to sit at tower with your thumb in your ass while she hard pushes the lane for level 2 with no available recourse
it just sucks like if i try to fight her with her e up she WILL win
and it lasts so long that by the time it's over she's pushed the lane up and can sit back while she waits for the CD; you can't punish her at all without jungler help
for an ability that turns her in to such a threat i feel like it lasts too long and has too little downtime early on that's just how i feel about it
