so, apparently we'll have to deal with n'zoth in some way to infuse it with that power.
as for a azshara, like the others said, she's in azuna.
i don't expect them to be a raid, because that would be pulling away from the main story line too much i think. azshara herself is probably stronger than n'zoth on a personal power level, considering he's the weakest of them and she's been infused with his power for 10k years and was already the strongest mortal mage in the world.
