Kayle is still a horrible pick for anyone other than Dyrus, just like when Genja popularized AD Kennen. Both picks are incredibly stupid unless you have the team comp for it. 99% of games do not.
Blocks damage for 2 seconds, for anyone (ult trondomere for hypertroll)
Ability that gives her AOE splash attack with range
She can go any lane (except shitty AD carry)
Can still deal damage as a support
highest level 1 AD of a ranged champion (if not it's near there)
amazing ass late game
>Jelly because you picked the boring sister unless you jungle her
