You can switch some mods. This is an endgame one. Since this shotgun has a loooot of status chance, you want to try to play the "[Condition Overload]" for Shotguns. Unfortunately every good mods for Shotguns cost a lot of endo.
But, anyway, 68k burst dps is quiet a lot because it doesn't count the dot. You can also play with [Shotgun Amp] as well if you want another multiplier.
If you are the Smite one, you can switch easily one mod for this like [Critical Deceleration]. But Galvanized Hability is quiet important because this will be the main source of real bust dps altho with [Galvanized Hell]. The precision Arcane is just better if you have it because the buff last 20s which is for me acceptable.
If you want to go to the Riven there is also a lot of switchable mods. It just depends on your rolls with it.
