Ranged AD mid > Kass
Assuming the player isn't a knuckle head.
True, but I generally kass-o-doodles with a strong jungler( I rarely use kass with a weak jungler or non-stun type of jungler) incase I come up against a bad mid. I personally think only Cait/Kog(and now varus)would be real big threats as far as AD range go due to their range abilities.
Best thing though would be a lane swap though. Then again Ive played Kass as support and wrecked with that. 11-4-16 was my last game with him as support.
I dont know, I mean I know theres a ton more counters to kass with his nerf to his Q and R but imo a great kass player can over come half of that with proper play and patience and working with your jungler to get you those early kills.
