Well I like to bounce around alot, but probably Kog'Maw (Favorite ranged carry) Amumu (Favorite tank and fun to play) Jax (For melee carry) and Malzahar (When we need some AP)
Ive just gotta say, I play this game ALL THE TIME. It consumes most of my life. My in game name is TacticalFacepalm. Anybody can add me if theyre just looking for somebody to play with because theres a good chance Ill be on. Like REALLY good.
