If you're doing Netherspite and have a shaman in the group, when Netherspite goes into netherphase, have shamans lay searing totem on one end of room, and everyone gets on the back of netherspite (opposite totem). As long as no dots are ticking on spite too horribly bad.. the searing totems will gain aggro and Netherspite will target them and netherbreath them repeatedly, and since it's an AoE they're immune to the damage.
Helps alot on the fight if done right.
