I honestly just disagree with the bold part above.
I just don't see how her being a Windrunner has anything to do with her gathering Val'kyr or trying to raise more dead/forsaken folk.
Sure, as an elf from Quel'Thalas she may be a little... uppity, thinking she is better than others but really, her name means nothing in terms of her attitude. What she has been through is more likely to be the biggest factor to drive her to certain things.
FYI: I feel I should point out that I'm no Sylvanas fanboy and that I don't even play Horde before I get accused of somehow "loving" her >_>
As for Vereesa and Alleria;
I wouldn't call Vereesa the "crow in Rhonin's ear". I'd call her his wife lol Besides, I doubt she's overly happy that he's now dead
Alleria also changed during the novels, I felt. She was of the "I'm better than you" attitude but through spending time with Turalyon and such, she did seem to soften and change a little. How long has she been off on some other world with him now? I'm sure she's likely changed a fair bit considering the places she could possibly be. Turalyon too.
