Are you really complaining about a gun that you don't have, probably never used and for what I understand don't know how it works? Unlimited ammo only happens on the KF raid under the Oryx shield where you become basically immortal. Everywhere else as soon as you hit 1 bullet left it will consume your armor and then your life in no time in exchange of you being able to keep shooting without reloading for a bit longer. It's a death sentence in PvP. It pretty much sucks as weapon everywhere in Destiny except in King's Fall. Not to mention that it has a pretty low impact for a scout, granted that it's full auto but scout wise for PvP the Tlaloc, Jade Rabbit, Hung Jury, DIS-47 and Tuonela are far superior alternatives. But rest assured that this time around the problem weapon wise on Osiris will be the Red Death. Pulse rifles are performing way better than any other primary weapon class at most ranges and that thing regenerates your life and armor upon a kill. Bungie just "created" the new Thorn by electing pulse rifles the weapon class of the moment. Party Crasher +1, Conspiracy Theory-D shotguns and sniper rifles with Ambush scopes and Hidden Hand will also be a dominant part of the "huge" variety of (~10) weapons usable on PvP.
