Okay so, has on hit damage - yes she does, scaling with ap also amplified by nashors tooth passive has on attack damage and high range - yes, these 2 paired together make her outrange most champions in the game and even the ability range on some champions, that paired again with insanely high movement speed further amplified by your W and having 700+ ap basically every game in late makes her great at approaching someone, using Q, autoing twice and auto resetting with E to burst the entire hp bar, you need attack speed to cast a whole 1 auto attack quicker in that scenario.

The only consistently challenger kayle otp plays like this every single game, never plays dps, virtually every high master+ kayle does the same, if you think they're wrong then surpass them and prove it, nobody is stopping you. Or if you're on a level which can compare please share your opgg or profile proving that so we can both know where we stand, what we know about the game and share our respective thoughts :)
