This gun is tremendous in both PvP and PvE. Like most guns in this game, you have to hit the head, but if you do, you own fusion range, can keep shotgunners at bay (this coming from a Felwinter abuser), and waste away more PvE enemies than you can with other special weapon types (not to mention making captains look like dregs), and you can do all this for longer periods of time due to the insane amount of ammo you can carry. I'm going to abuse this gun and get the most fun out of it before everyone starts realizing how good it is and starts using it in the Crucible, or Bungie nerfs it.
