When the weekly heroic strike was set on "The Nexus" I did it with a clanmate, and I used my primary level 28 Hunter(right now 26 due to armor swapping). I had to do it twice cause I was dropped right before rewards were handed out. The second run, I was able to stay in the lobby and finish the strike, and as the boss fell, I was given a legendary chest engram as a reward. Once in orbit, I logged off and turned off my xbox. When I logged back in, the chestpiece engram was gone.
