They never nerf, Bungie always balance ;P (yeah right ??!!! WTF) If a weapon is too strong in PvP the nerf carries over to PvE. Appart from gjallarhorn and Ice breaker, that were truely game breaking in PvE. Its the only arc burn primary in the game right now that is usable in the end game activities. If they don't want us to use it, they need to offer better choices of arc burn primary.
