double the range and it could be useful, short of that shotguns are the unwanted middle child of small guns. Also whoever decided shotguns are short range is an idiot, shotguns are effective at up to 120 feet.
I change my mind, I think it should have knockback instead. 50% or 100%, this gun is deserves it, shotguns have never been anything good for PvP. However, for PvE, in its current state, I do think it's okay. I also think it would be fair since frags have 100% knockdown/knockback chance, and only 4 AP is required with BRoF.
I would be okay with giving shotguns a buff, it will only help the PvE players anyway.
Ranges are all compressed to fit the maps.So it is limited relative to the other guns.Perhaps slug ammo...
In the movie, shotgun is mid range, deadly and slow. I think it need much more damage, more AP and a little range
