They still say "You seek further instruction in the manipulation of the Naaru's power, <name>?" when you go to learn from them. Shouldn't that be updated, considering they've allied with A'dal and the sunwell has been restored?
I don't know, isn't it still technically a Naaru's power? I mean, given that the Sunwell was restored with a Naaru and such, and they were originally siphoning a Naaru's power, they might still consider it manipulation of the Naaru's powers and all.
