Cleanse or [Primed Point Blank] can be argued over savvy because savvy only gives you damage bonus after first shot.

Using cold progen to create a corro-cold combo using only two slots. (Corro-cold is the best combo for raw damage)

[Primed Tactical Pump] basically doubles our dps and ironically increases our fire rate more than spazz.

Using [Toxic Barrage] so we can get more status on target, this can of course be swapped with toxin 90.

Seeking force cuz why hit 1 enemy when u could hit 4? This can be replaced with savvy/ [Primed Chilling Grasp] depending.
