CM is probably considered one of the best supports in the game. She has a lot of potential that nobody gives her credit for. When people say "Crystal Maiden can't carry lol" they are wrong. Prove it to them. Make them writhe in your icy grasp as you defeat the opposition and claim your rightful godlike.You probably won't get a godlike but it IS possible.

Even if you don't play as hard carry, you should still end up with ~5 kills in a normal match.

Play aggressive, steal kills and win the game.
