First off, I know that statistically speaking, us Hunters get trumped by other classes/specs on this particular fight, but I doubt my raid would want me to bring my 385 alt Mage without a legendary nor 4P (unless they do?).
For those lucky ones who have started on the fight already, what's your recommendation for spec and just gear in general (as well as reforges)? Also, some information about your 'rotation' for the tendons would be nice too, as well as the damage you do each plate phase. Tendons aside, is the rest of the fight not important at all as far as DPS goes?
