Shotguns are seriously underrated in PVE, I've been using slayers fang a lot and I've noticed that with very few PVE exotic shotguns duality needs an update. The gun is strong but it needs to pair with scorch builds. So it should have on black wings, proccing that should give you 5 seconds of scorch rounds. This would pair well with no backup plans. I'm aware that lord of wolves exists BUT that gun uses a TON of ammo, and to me I like more pump action style shotguns than heavy burst ones. It's never been updated. Duality needs an update.
