Weekly raid: Anub Rekhan

Strategy:

Although doable with two tanks, three tanks are ideal for this encounter. One of them should tank Anub'Rekhan, while the others tank the Crypt Guard adds and the Scarabs that spawn from their corpses. In the 10-man encounter, the two Crypt Guards are not present at the start of the fight, making the third tank unnecessary. A hunter is helpful but unnecessary.

The main tank engages Anub'Rekhan and drags him back to where he was standing originally (note that tanking him against the wall can cause evade bugs should the tank be impaled). In the 25-man fight, the other tanks pick up their Crypt Guards while the DPS focus them down. These should be tanked and killed relatively close to Anub'Rekhan. Due to the acid DoT the Crypt Guards apply infinitely these should be killed quickly.

After this, the raid should spread out in a semi-circle around Anub'Rekhan to minimize the effects of impale. Mages should be ready near the Crypt Guard corpses to frost nova the Corpse Scarabs as they come out; the offtanks should be on or near these corpses to pick them up. Ranged DPS should focus and kill the scarabs before returning to Anub'Rekhan. You should have a decent amount of time to DPS Anub'Rekhan before the first Locust Swarm. One player—ideally a Hunter—and a healer stand 30 yards from the main tank on the edge of the room past the ring of slime. When Locust Swarm is cast, all players must immediately run from Anub'Rekhan to the other side of the room and remain more than 30 yards from him for the next 20 seconds.

The main tank, when he sees the Locust Swarm cast bar, must begin kiting Anub'Rekhan along the edge of the slime to the other side of the room. The hunter should have Aspect of the Pack on. The healer should move with them and avoid getting any stacks of Locust Swarm in order to be able to heal the tank and hunter should they be hit. A warrior tank should use Intervene to gain additional distance. Locust Swarm ends when Anub'Rekhan reaches the other side of the room, where he should be tanked as before, with the raid spreading out in a half circle. Another Crypt Guard spawns during this time; pick up and kill it. Again, Mages should be to be aware of Corpse Scarabs spawning from it. After this, the encounter continues, with Locust Swarms coming every ~90 seconds until Anub'Rekhan is dead.
