So will it be the general or yogg-saron that does this during his encounter?
obviously, herald volajz isnt the prime faceless one, and IIRC, yogg-saron is responsible for their existence. which, if not both, will end up doing the insanity effect to the raid in ulduar? unless we already know the general doesnt do it?
i see the insanity effect splitting the raid up into 5 phases, each with 5 people(or less, depending on if you're going w/ <25) and it being like fighting against preistess delrissa in MGT
