tanks should swap boss only when add appears, right?
as the guy above has wrote, no, swapping produces the adds, tanks only swap once the male arrives, if you swap prior to that or lose aggro then the adds will appear before the male and the red pool (red pool comes with male).
so basically only swap once Jealous Male arrives, not before.
slap any dps that over aggros, its their fault not the tanks. they have aggro dumps for a reason and should be using them on CD., and also controlling their dps.
