I know this kind of an old thread, but maybe someone can give me some pointers :]. Currently running this instance with my team (prot pally, Resto shammy, Arcane mage, 2x Elemental Shammy), they are level 85. I got the first two bosses down, quite easily. But I can't get past the third boss. As soon as she summons the dragon I get wiped. My team get's own by the fire on the ground, it does too much damage (or I'm responding too slow ...).

Are there any tricks to this boss?
