That gun is WAY too strong on PVP. It's honestly not fair at all. It's rate of fire coupled with its range and ability to regenerate special ammunition unbalance the playing field and make practically every other shotgun pointless by comparison. A gun that's this easy to obtain, yet still randomly given, should not lord over PVP the way it does. They say levels are balanced out for PVP, but as long as gun stats and perks aren't normalized as well then we can't truly have balance. It is far too easy to get CQC kills with it. The invective can let off 3 shots before any of my shotguns can get into kill range, it's unbelievably infuriating.
