Here's the VOD for day 3.
Calphayus seems to be fixed and in satisfactory working order. Raptus is pretty easy now.
As to the dread masters, we think we know a lot of the fight. We're double tanking raptus and calph, solo tanking bestia. The problem we were running into was execution on tank swaps (and class deficiency inasmuch as assassins don't have a charge). We're considering 3 tanking the encounter on sunday just for an easy way to see the rest of the phases and to see if there's an enrage.
