I am not flaming, but I really do not think toribash requires any skill, just luck and a responsive mouse. Tell me otherwise if you will but really you can never predict your opponents move at any time. Right when you think you have the win, you get DM'd by a zombie limb.
As for rank, that is only a symbol of how active you are. Jepoy would be rank 2000 if he hadnt played every waking moment of his life... which is pretty sad. Now, Im not saying that a white belt could beat a master because part of the game is undertanding the physics, but once you get to brown everyone is equal if they arent a sped.
