Other than the DOW, shotguns in general need a shorter falloff with the damage.
The DOW. being a legendary, feels underpowered as hell. 3 shots to kill, IF every shot is dead on target.
I honestly wouldn't expect them to release any major updates until the end of this year. They've got some major coding to do among multiple other things.
Go be a FNG somewhere else.... The support system is overloaded, and will be for sometime. I had the same issue and it took them over a month to solve it.
