Any void fusion or shotgun with decent pvp perks will work
Void machine gun or void rocket launcher. Tracking, cluster bombs help in pvp
Void primaries only come from the raids
Any void sniper with good pvp perks will also work
I'm a below average crucible player, and I did this part of the bounty with a void fusion and void jolders hammer while running voidwalker warlock
Mostly I hung back and tried for assists as much as I could since they count for points also
I ran away from anything I didn't have a clear advantage in
I played slow and smart, and kept my kd positive
it took a bit to get the hang of the new way that ammo spawns, but once I understood it, I was able to put myself in position to stay topped off most of the time
Have fun and good luck!
