If it's your WHM tending to get wacked he could try using med 1 after white fire hits then about 1 or 2 seconds after med 1 start to SS the MT followed by regen on MT. The add will have spawned with no HoTs ticking and the MT will be buffed for Revelation. Also after Regen hits MT it should be time to regen OT followed by a cure on MT to recover from Revelation.
