If you're using a Void Walker or Defender, that helps. Otherwise, use your favorite most effective primary, and void elemental special and heavy weapon. Use a cautious playing style on the battlefield. Let your teammates spread out and capture nodes, while sitting back picking off whomever comes across your sights. At the time I used my Grim Citizen, a rare void fusion rifle, and the Truth. Snipers also work great in this situation. Good luck...
