olaf is
really strong all game, unless he is ganked by multiple enemies or caught out. for example i just played a game with olaf, and except for one death to the enemy fizz i got 8 kills straight in my lane alone. i then followed that up with 5 more kills but the enemy team got smart and started grouping me so i was dying on top of getting kills. over all he is a really fun champion, really strong and the reward for playing him is not bad.
