Kayle is a very good champion, but I hate her early game very much. I feel that she is a champion that you have to play very cautiously at the beginning because of how easy it is to take advantage of her since she is super weak in those moments of the game. But I've played against countless Kayles where they easily do 1v9, it's crazy how broken that champion is in late XD

what tier are you? and on which server you're playing?
