My guild does it with 2 tanks on Gormok. The pally takes the first 4 and I use Last Stand on 5 and 6, Shield Wall on 7 and if I didn't time it properly I call for a pain supression on the 8th. When Gormok has 4 stacks of Rising Anger you need a cooldown on you to live through impales. I like to pretend I'm a paladin or druid tanking this without any outside cooldowns. After I die to 60k damage in < 1 second though and need a battle rez I get shocked by to reality.
