I guess all we can do is keep trying. If Gormok doesn't kill us, half the raid gets sprayed with Paralytic Toxin right off the bat, wiping us. If we don't get killed by the first wave of toxin, too many dps stand in the poison clouds and die. If nobody dies, too many are frozen by the toxin, and can't dps, so Icehowl comes out before Dreadscale is down. His first Icy Breath then proceeds to wipe the 2/3 of the raid clumped up next to Dreadscale. More gear, and more practice, and we'll get it. And believe it or not, our guild has done 10 man heroic runs and killed him before. BTW, love the new t10 armor models: http://www.mmo-champion.com/news-2/tier-10-armor-sets-hd-preview/msg1571580/?topicseen#new
