It's a bit to convenient for Zandalari, who already share the model of Night Elves, to be going around using such iconic spells such as Starfall (which, according to some, have the same coloration as moon magic in game, but a different, improved graphic than the Druids version.) when said character is a priest.
It seens we are getting closer and closer to confirmation of Elune beng some sort of ancient Loa.
I do have to wonder if we will run into a High Priestess of Elune from the Trolls, in whom which is favored even more than Tyrande. I find it unlikely that Tyrande is still the favored, considering her inability to heal Shandris in her short story, which was a fairly big deal considering how they made a point of saying Tyrande was never turned down the power to heal in WotA.
