it is time to disable champions in ranked without a mastery
level three should work. i know many people dislike that idea but this has to stop. i just had a galio and a taliyah in my game who both played the champions for the first time. taliyah destroyed two teamfights for us by splitting our team in the jungle. galio fed 14 kills and tried to 1v1 the enemy carries nonstop and kept losing. if people dont stop being stupid we have to start protecting them from their foolishness.
