Xin and Warwick for me.

Could be luck based, I always end up as the initiator on bruisers that I like to get a bit of damage on before stacking tank items.

After failed team fights or lack of escape from ganks, I end up useless as a low damage, low survivability melee that the other team laughs at.

Jax and Shaco.

Kennen.

I own him, I like him, but i suck with him lol

For some reason I just can't play Urgot............only Crabgot!

Lee sin. 'cause he's not real.

Kog Maw

Kayle -_____-

Teemo. Just because I keep trying to kill myself.

Shaco and Xin Zhao

Shaco I fail at ganking with, and Xin I think I skill him wrong and/or get the wrong items on him, or I don't play aggressive enough or something
