The new Prophecy Dungeon weapons are so broken in PVP. Obviously, they toned down the inherent trait compared to PVE, but combined with some of the perk combos, these weapons are just out of control.
I spent most of last night farming and got The Sudden Death Shotgun with Threat Detector, Opening Shot and Range masterwork. Combined with the Inherent perk that adds damage to the bottom of the magazine, I can map pretty much anybody.
I also got an SMG from the same encounter that has Dyamic Sway Reduction and Onslaught. Combined, again, with the inherent trait that gives increased range at the top of the magazine and increased damage at the bottom... this thing shreds.
