Definetly took inspiration from Prinn with what I'm currently running. A lot of room here to move things around especially with artifacts. 

For clearing out patrols and terminals I use the  (Heavy Plasma Rifle) and when I get to bosses I swap back to  (Mini gun). 

I've been testing with and with out Cobra's Hood and I have just had consistently better numbers with Rockets own slot 5, and using the (Gravity Mine). 

You can also swap out the shield for a  if you dont need the extra defensive stats. In patrols I find it just better to run a shield.
