Hate to ask this question so late in the expansion. My raid team is attempting to clear Ulduar hard modes. There's a bit of confusion on whether or not you are required to kill all of the keepers on HARD MODE in the SAME lockout in order to gain access to Algalon? Or, does the player with the disc only need to be present when the four keepers are defeated in hard mode (regardless of the lockout)?
Thanks for your help.
