1. Lord Marrowgar requires 1-2 tanks, 2-3 healers, and DPS to focus on killing Bone Spikes while avoiding Coldflames and Bonestorm.
2. Lady Deathwhisper has two phases - tanks pick up adds in phase 1 while DPS drain her mana, then it's a tank and spank in phase 2.
3. Deathbringer Saurfang is easiest with 1 tank, 1-2 healers, and DPS spread out to avoid activating Blood Nova and focusing down Blood Beasts.
