Axton. His skill trees are bland, his specialties are bland, he's just uber boring. --- >X< Leader of The Dream Team >X< "A game moves pretty fast. If you don't stop and teabag once in a while, you could miss it."
Roland was the first character I played as, but I found him to be atrocious. Brick was at least good at the beginning of the game. Roland just never had a decent time. (Mind you, I only ever played single-player or with just one other person split-screening).
Of course, not one character can come close to Mordecai. <3
