I think it's good I tried it in SP Void missions and it works pretty well.
The only downside is that it can't take down literal hoards of enemies very easily.
If you feel you want to you can switch out some stuff for [Primed Firestorm] I mean meh.
And there isn't really much you can put into the exilus slot (I think at least) besides [Hush], [Terminal Velocity], or [Agile Aim]
Infinite Ammo is a winning trait with the ladies.
