Perhaps no nerf to the gun itself is necessary if it simply requires heavy ammo. What do you think?
Then pve players will get affected by this change, for no reason at all when it is a problem in pvp only. All Bungie has to do is either reduce the damage of release the wolves perk in pvp ONLY, or change it back to how it originally was where you need a kill in order to proc the release the wolves perk. Problem solved
