I noticed that my friend's Vex Mythoclast does not fire like it's supposed to. Now I'm not talking about the glitch where it fires like a normal "special slot" fusion rifle. This is different. In the linked YT vid, he is shown firing one entire clip by holding down the fire trigger once. Then I empty mine the same way. Mine behaves normally-no charge up time and about 6 to 7 bolts per second. His fires far slower and seems to sputter, like some of the bolts are "duds." This is what we have tried so far: 1. Switching to the special weapon and switching back 2. Switching to the special weapon, firing and switching back 3. Changing to a different primary and switching back 4. Using a different Xbox One controller 5. Changing how the perk columns are setup Nothing solves this issue I received mine many months ago, before House of Wolves. He acquired his recently, after the HoW expansion. That shouldn't make any difference theoretically as the code should be the same. If anybody can offer anything it would be appreciated. The only thing that would be left to try is to dismantle it and get another drop from VoG. Or perhaps he can get another made from the exotic blueprint vault in TTK. I don't know what to tell him here.
