olaf srsly have no counter play against.
single handedly every time, the guy who wins has olaf, and in very rare occasions its someone with crap tons of lvl 3s.
yeah nothing wrong what so ever. its not even fun to play against. you just guaranteed to lose.
Possible olaf nerf:
Consider making him 5 gold? and that maybe will be enough, because he clearly more scary then master yi or zed. or any other 5 gold champ
red buff, 6 mages etc
