There's no Mind Control Pillars for Instructor Razuvious in (25-man) Naxxramas

Just did (10-man) Naxxramas, reformed raid for (25-man), and we came out thinking we’d have no problem doing Instructor Razuvious in our (25-man) Naxxramas. But when we reached the encounter, we found out that there’s no Mind Control Pillars. How are we suppose to do this fight without the Mind Control Pillars in (25-man) Naxxramas?

10 has orbs 25 doesn’t.

you are intended to use priests to mind control the adds in 25man

Yeah, you use two priests. Did your raid leader just not research the instance?
