We do have a "main" prot paladin, but he is holy for Brut+Felmyst+Twins anyway! Which is half the instance. Our MT goes Arms on Brut many raids. Our locks are always taking turns at Affliction when needed. Our main (and only) holy priest is often shadow. Even one of our BM's goes survival if I cant make the raid.

You really don't need to make many massive raid substitutions when BC throws so much gear at you. Every player should have their offspec gear ready, and offspec knowledge/experience to go with it.
