They pushed him off then stayed up there for a while though. I had a guy stay up top when I ran it after the other two of us dropped. The minotaur that spawns up there killed him and he left as soon as he realized we couldn't get to him to revive. The other guy died 4-5 times. I revived him a few, then he died at the last spawn of adds out in the open. I decided to drop the boss on my own on this point, but accidentally slipped off of my usual hiding spot and died mid air. When we respawned the second guy left. I decided to try again tonight.
