Finished this a few days ago. If you have a friend. one of you can hide under the stairs in the far back area . No one can get to you. just don't fall. Then LOCK AND LOAD, bring ammo refills. Since it was my bounty and it was for thorn i ran around with a hand gun and used my friend as a spawn point. He hasn't gotten the bounty yet but as soon as it happens i will return the favor. For the crucible i used a void shotgun/void fusion/void rockets and played defensively. I agree stay with the group. Being a void warlock helps too. That void Kamehameha is boss when they gather together. This strategy was useful on 6v6. the capture pvp are much more team based so the enemy at some point starts rolling in squads.
