I just posted a new help thread seconds ago about my V8 glitch. It does NO DAMAGE against fallen ultras level 6 or higher. It's fully upgraded I'm a level 30 hunter. The V8 will work fine in no spawn zones, public events, against hive and vex, but if I'm in the field and see a lvl 6 fallen i have to switch to my secondary or melee. I have 4 legendary primary and 4 legendary secondary all work fine except the vanquisher. V8 is a great auto, but this glitch drives me insane!
