75% of level 4 mission runners are using either Raven Navy Issues or Dominixes. 24% are working on getting one of those two ships and the remaining 1% are far too rich for their own good and are missioning in Golems, Bhaalgorns or Nightmares.

Doesn't do stellar DPS but will shred anything smaller than a BS faster than you can lock new targets and will chew through bigger stuff like structures and BSs quickly enough with a full flight of Ogre IIs.
Cap is a problem if you run the AB and the repper all the time but there's no real need to do this, the guns add about 300 DPS if you have good skills which certainly helps.
