I heard it's a faceroll but haven't had a chance to try it out since the Horde has had control of TB since Cata launch. Not complaining, loling at it's brokenness rather. When Blizz fixes it or the Allies get extremely lucky I will go in with my guild and knock it over.
PVP related bosses aren't really meant to be a challenge since they have a large loot table and guilds can't farm it for specific pieces of gear.
It's archavon 2.0, get in there, get loots, leave. Though I haven't tried pugging it, getting it done first week into cata is sorta easy, since first week into wrath there weren't even a hundred 80s my server
