I didn't like this expansion as a whole, I try my best to keep an open mind, but quite honestly, it was the worst expansion ever. But you could argue that this entire expansion, with the Jailer and Lich King and the Helm of Domination, the spirit healers, the afterlives, and Elune's true nature, has been a series of repeated retcons by that same token. I liked this novel because I think Golden did work very long and hard into weaving Sylvanas's background, and she did the best with what she was given, which is I suppose what any of us could do. I think this Sylvanas is at least more interesting than the one-dimensional, cold-blooded emotionless psychopath who kills people simply for sadistic pleasure and power.
Agreed, Golden's writing may not be perfect, but I do think it is far better than most of Blizzard's other writers. Still, I wonder what would happen if she openly told them that she disliked the direction they were taking Sylvanas and the storyline, would they listen to her? Or would she just lose her job immediately?
