me (hunter) tanking it with stamina (pvp) gear and gems and a normal survival raidspec. buffed over 40k hitpoints. the killshot available from the start makes up for the geargimp threatwise. the pvp meta gem with increased movement speed to get to those orbs even faster, and 3 points in rangetalents make orbhunting no problem. just make sure you are NEVER in melee range of the prince. our healers don't have a problem keeping me up.
