I did read it...Well, some of it... I found it absoloutely horrendous and didn't read all of it. I did fight myself through the "Meeting" chapter and nowhere as far as I'm aware did golden explain why the forsaken - or the desolate council - would view Calia as a leader. Or even as a contender to the current "throne". All there is, is her name and that's it. Also if we're going by the "medieval power structure" argument, they also knew how to hold a grudge, entire families were slaughtered and killed because the missdeeds of one person, all over the world, it was common. The name Menethil by all regards should be a shitstain on forsaken culture, but apperantly it is not, and I bet if Arthas came back as a living lightforged human, he'd get the full support of the forsaken with Anduin behind him.
Also the entire Horde plot feels like it only exist to further develop Anduin,Calia,Genn and the rest of the Alliance, the horde leaders did and said nothing, acting like mindless drones, we get no insight on their thoughts, except for one. And she keeps on rambling about being the first female warchief and how good it is if everyone is misserable. This is only a "preview"(a big fucking preview) and hopefully we missed many important aspects, but I seriously doubt it when it comes to Blizzard and Golden. Neither of them knows how to write a intruiging story
