I'd be curious to hear the "intended" method by the devs for doing this fight since it becomes moot next week.
Double points for a vid of the developers doing it with the "lower" classes for each role commando/merc healers, vanguard/pt tanks (worst CDs of the 3), scoundrel/op /shadow/sin sage/sorc DPS, means no armor debuffs no scramble field no LOLNOFORCESHROUD and no bloodthirst.
