We do 3 Fireball exactly to have more time because we dont see any HP nerf on the conflag also if a damage dealer is in the conflag its way to less DPS there... hmm you say stoneskin help but if our healer buff stoneskin the MT will die for sure cause he have to be perma healed!
Bad heal and/or bad tank. During Conflags, I only have to heal the MT occasionally as a WHM, SCH can handle it without any bigger problems. Perma Heal during Conflags seems very suspiscious. During Phase 1 I Stonekin all people and whoever gets fireballed at Phase 2 will be restoneskinned. Easy 3stacking.
