Did this guy on Herioc the other day definately the hardest boss in Herioc MGT only strat that worked for us was assign one person to kill the adds until they spawned to fast then switched all DPS to the boss and hope you don't die to the overload.

Don't forget he's auto attacks are actually arcane (Sort of like how the first boss of Mana-Tombs is all shadow) so resist gear could help, a Druid doesn't really need to be in bearform to Tank, since armor means nothing for this fight, so tell him to just tank it in cat to help with DPS.
