The 180 (Malfeasance) doesn't really. It does good for ad clearing, majors, and champions and if you use the Hunter exotic it also does well for boss dps. Though Sturm could use some changes. Maybe kills with Drang grant massive temporary buffs to Sturm and grant 3 stacks while other primary/special weapons just grant 1 stack.
Whilst I agree malfeasance is great I was thinking more stuff to synergies with our builds offering either 3.0 verbs baked in or maybe play around with using our class ability to make gun do (Insert cool trait here)
