Garrosh: In the "other realm" you can AMS two annihilate in a row if you use it just before the first one hits. You can Dark Sim players who are MC'd. If you Dark Sim the first CL from the shaman it will last until the next wave of adds are gathered to get max dmg from it. Army can take a lot of heat off the add tank.

Galakras Make sure to deathgrip the bonecrushers off the friendly npcs when they cast fracture. Time it so you grip after they have started channeling fracture, otherwise they will just run back and redo it. When the king is targed by This in melee range just run a bit out and grip him to prevent him from dying. Also remorseless winter works on most mobs in the waves.
