After having DC issues all over the place we finally pulled and lost our tank to 3 mobs when they enraged.

We had myself on my paladin and 2 resto druids healing, the healers and tanks were easily out gearing the content by a landslide and we shouldn't have had any problem. The tank was getting spammed healed by all 3 of us, however, it still wasn't enough to keep him up through those little trash enrages.

I can only imagine what Marrowgar had been like if we would have been able to clear the trash to him. Once we wiped twice, the world server went down. Was pretty ridiculous to lose a tank on the first trash pull.

All the ICC dungeon and raid content is MUCH harder on the PTR that intended. We changed some behind the scenes creature damage values and I haven't modified the WotLK content to account for those changes yet.
