I don't think so. "Balance up" only works for a game that's purely PvE, which is why Borderlands has some crazy overpowered guns. Throw PvP in there, and "balancing up" reduces time-to-kill and waters down the multiplayer experience. Basically, it becomes CoD. These changes were necessary because some of the guns were the absolute top choice for their corresponding activity (Thorn for PvP, Gjallarhorn for PvE). They severely overshadowed any other choice one could make and, if you weren't going in using these guns, you were immediately at a disadvantage. In a game with so many guns to choose from, so few of them shouldn't reign supreme.
