So yeah, I've tinkered around with my loadout to see if something specific was triggering this. My own personal results show that it just doesn't work at all in PvP at least. So if you could look into this, that'd be great! P.S: Fusion Rifles named anything other than Telesto are incredibly, incredibly underwhelming. Anything outside of Shotgun range is never guaranteed to even break shields sometimes. Far too inconsistent, needs a buff before it can be a competitive choice for a special weapon.
What's that got to do with scavenger?
