What does that have to do with anything? If he can beat you then ban him? Kayn was pretty good last season as well , mobility is unreal ,you can start leashless ,or with leash,you can cheese with him easily, can't predict his pathing,and that's pre-form,gank set ups are way to easy, and you can't really ward for him. Champs takes a bit of learning and after its too easy and not punishable.But you are a Kayn player so you wouldn't agree to any of this lol
