Not gonna lie, it depends on the map, but usually fusion rifle just because of the versatility, although: 1) I rarely switch to my special weapon. And which primary I use depends on which bounty I'm trying to complete. 2) I acquired Swordbreaker from CE last cycle, so I'm in the process of leveling it up, so, yeah, lots of Control... Also, Hive Disruptor (enhanced damage against Majors) is awesome.
