I'm 53 cleric and was there with a 47 wizzy friend, we were camping for rings from Nosja and Daman (both got Nosja's ring and he got Daman's ring in 6 hours); we were fully buffed and FM when I pulled the enraged relative. It had apparently spawned and got hung in another room, very odd considering it usually pops when you kill something. Anyway, we killed the relative and 2 dancer adds. Both of us were battered and completely oom but we did it. Might be easier with pet classes. All we had was root and nuke :)
Not bragging, just saying it can be done even if you can't get a tank.
