Hey m8,
This might help you.
No matter what raid setup..
Tank gormok at the door so tank doesnt have to move him so all can start nuking asap.
When snobolds spawns make sure the one with the snobold on his back moves to the melee so the melee can still hit the boss with cleave etc, rest of the raid should swap to snobolds to nuke em down assap.. each snobold up is 15% more dmg to the tank..
Also take 3 tanks swap rotate on 2 impales.. or they will die at some point.
