stickboy covered it really well, but I'll add some.
Lilith is basically broken. With minimal effort, you can never die, and with some easily obtainable gear, destroy the game. Remember when GBX called Gaige girlfriend mode? Lilith is actually girlfriend mode.
Mordecai can out dps Lilith, but he has minimal survivability, so if you can't aim you're screwed.
Roland is the best balanced, imo. Good skills, good coms, good damage (that you have to work for), good survivability, and the best com in the game: the Atlas loyalty com.
Brick, to me is just as boring as Lilith, but for different reasons. Not a fan of his as, or his skills in general. --- http://s3.amazonaws.com/br-cdn/temp_images/2014/01/05/EddieLacyBig.gif Dancing makes me sweaty...all over ;)
Quite possibly the most overrated skill in the first game.
bl1 was pretty overrated so
lol bl2 kid
The only issue I had with BL1 was the enemies glitching out of the Underdome because it has so far prevented me from finishing the larger challenges and completing the Achievements. Those are the last ones I need. --- "If your going to ask someone to save the world, make sure they like it the way it is" https://soundcloud.com/shake-like-e
