Any tips on doing the 500 crucible void kills slightly less painful?
Shotgun/FR and HW in void.
If you have void skills use those.
Play Control or Rumble.
Abuse HW ammo.
Hassle control points for kills.
Play earlier in the day if you're having trouble (higher skilled players tend to come online in the evening).
Play with a fireteam if you can and work together. Get the other players to take down shields for you, a Titan to use supression grenades and weapon buffs, etc..
