I just played an optional mission in Borderlands 2 called The Bane and as the mission reward I got a cursed gun called as the Bane itself. The Bane turned out to be an SMG and since it is cursed(my opinion), it immensely reduces my movement speed whenever I wield it. It also got poor accuracy and the only advantage I can see is its high damage potential.
So I thought about selling it but I just needed advice from somebody who already beat this game.
1) Should I sell the gun?
2) Do the drawbacks outweigh the advantage(s)?
3) Will it become useful later in the game?
I'm playing as Zero, the Assassin and because of this I haven't quite used SMG-s. So if there are some plus points I'm not seeing in this cursed gun, please let me know about it.
