Yeah, I was so-so lukewarm about BL too. Played 1/2 of it with the same damn rifle I found near the begining of the game (think it was 1.4X scope, 83%ac, 80 damage per shot, 110ammo clip, and a faster rate of fire than normal). Finished the last boss with just two clips :0.
What I didn't like was the skill tree. Most of the stuff just boosted one stat or two but there wasn't any epics spells or talents. Whoopie one special for each class. Can't even come close to being compared to Diablo's 2 tech tree.
