Ok, good to know. So it seems that the biggest problem with perma-Mist Form for Raptor Farming would be the interrupts (something those raptors are REALLY good at).

Magnetic Aura helps to prevent energy loss from Mantra of resolve. I generally cast Magnetic just as the bulk of the aggro is almost on top of me. Magnetic is 75% block, so there are times when energy can be a problem, but not often.
