I'm actually surprised by how much I enjoy Kayn
i have 0 interest in kayn as a character (trying too hard and failing to seem cool; rhaast is godlike 100%) but he's really fun regardless of what path you take
feels and builds a lot like a juggernaut (very health-AD heavy build), and has VERY HIGH carry potential with the raw damage he's able to do. possibly the best cleanup in the game, E scales down hard that you can use it constantly and keep chasing people.
i think he's a little too high numbers wise but not really that overloaded
i would not mind at all if rhaast was a template for future juggs and melee carries, he's insanely fun and satisfying. i accept this champ with open arms, finally a new champion i can love to play, very good job riot
