I cant agree that the Boltshot is OP, it requires timing and a little bravery to use the Boltshot as a shotgun, since it wont fire the chargeshot until fully charged, and you gotta be pretty close to use it, and if you miss, your completely exposed.
DMR needs nerfing, but only slightly, an ROF nerf so that its slower than BR and being removed from SWAT would make it acceptable.
While im here, I feel that the Forerunner rifles are far to weak.
Supressor should apply more knockback effect, the replacement for being knocked out of zoom, this would make it viable as a gun that makes use of its name, making up for its weak damage and fairly crappy range.
Lightrifle just needs buffing, everything outguns it, I get the first scoped shot on a DMR user and he still kills me, and the BR just kills faster outright, as it stands there is NO reason to take this thing over even an AR.
