Hm. I know about the random target Perpetual Ray in P1 and P2, but never though it could be blocked. Are you sure it can be blocked by standing in front? In P3 it only ever targets the MT no matter where you stand, but there's really no reason for the MT to move around in P3 anyway. I'm gonna have to relay this info to our healers and see if they felt P1+2 to be any different when tanks don't stand right in the front.
