Thor, hawkmoon, vex, surros, v8, the devil you don't or the chance with luck in the chamber, all of these are much better pvp guns than fate bringer. Firefly is almost useless in pvp, people need to be hugging to be hit by it. Outlaw is a common but great reward perk for any gun, but faster reload for good play is not close to op. Fate bringer is a great pve gun, where firefly shines, but meh in pvp with its low stability and slower rof, compared to the hand cannons it's not even a contender. If you got rolled by this gun it was prob by a skilled player that would have rolled over you with any gun.
