One of the three drakes in blackwing lair, pretty easy if you have a good strategy.

Abilities

Flame Buffet: Deals 139-162 damage and increases fire damage taken by 150 for 20 seconds.

Wing Buffet: Deals around 540-940 damage in a cone shaped effect knocking them back.

Shadow Flame: Deals around 4000-5000 damage in a cone infront of the drake.

Fight

Make sure the entire room is clear before pulling Firemaw, You will be pulled him back facing the wall next to Broodlords gate. This is so that your MT can position himself so the healer's can heal him while being out of sight so they don't get hit with Firemaws AoE.

Your off-tanks should be positioned one behind Firemaw and one on the other side of the gate. By tanking Firemaw in the right position your MT is not knocked back at all when hit with Wing Buffet.

By not flying back at all he can immediately get aggro back, this makes the need for Off-tanks much less. However in the case that Flame Buffet stacks to much have one of your off-tanks move in and grab aggro for a while.

Good luck.
