I don't know that I'd describe it as an 'encounter', it was more an experience The one time I've done it was a total zergfest I think I personally died 16 times by the end of it. He past 40 stacks of Growing Fury well before he died (I stopped paying attention after that).
Basically I'd rez and get a few solid shots in before being obliterated by Piercing Roar (which as far as I could tell was unavoidable). So many skeletons... so many skeletons.
It seemed to take forever too, so it was an experience, but I'm not sure it's one I'll rush back to in a hurry.Being on a PvP server may have made the whole thing a little more challenging too.
