A thought on Kassadin
I'm not saying he's OP/UP. I'm saying that, I always see this guy getting nerfed because his mobility is too overwhelming or buffed because after the nerf he became pretty bad. I swear I can't remember ONE patch where Kassa didn't get touched, and this is all because his 2 sec CD blink. A champion that gets always nerfed/buffed in every patch makes me think of a really bad designed champion. So I was thinking, why are they not fully reworking him? Why don't they just move his R into his W and make him a passive-active ability, with a brand new R? It would be like
Passive : Every autoattack, Kassadin stores energy from the void, reducing by x seconds the active effect. If he continues to autoattack with Rift Walk ready to be casted, he stores a Rift Walk charge. Max 3 charge ( so he can keep his mobility for a team fight while having to fight for it by AA )
Active : Kassadin blinks in a target location, dealing AoE damage. ( add cc maybe? )
R - No idea (really.)
I'm not a good designer and this is probably a bad Kassadin rework, but it's just an idea of how it would be like. What do you guys think? Is he a bad designed champion? If yes, how could you make him balanced?
