So after a couple attempts we got all of Halfus' drakes down pretty consistently (excluding Slate which we don't release) with a 2 tank / 3 healer comp. We don't have a mage. With this in mind, how do we get the interrupt after the furious roars? This amount of raid damage simply dominates us at this point. Everything else is solid but we are consistently wiping at around 30% because we can't get those interrupted. We have a ret pally who bubbles himself in order to run in and interrupt one of them, but after that we have nothing. Is there anything short of PVP trinkets we can use to avoid this probably and get the boss down?
