In reality it's a PvE gun that you should use at certain points of certain activities. For example it won't be so great in the Aksis fight because you can't crit shanks. But on siege engine if most of your team has one you'll wreck all those dregs. Having a dude with a raze lighter will still be be great too. Guarantee this gun will get cried about in crucible. But much of the real crucible community will go back to the guns you mentioned and you won't see it much in time. But will for now due to the light it drops at.
