I’m thinking specifically of the revamped Andorhal quests, where Sylvanas sends her val’kyr to raise the Alliance troops and civilians fighting in the city. They were forced into undeath and used against their former comrades, and there was nothing - at least in game - to indicate they were given any sort of agency at all.
While I’m not a big fan of Garrosh, I’ll give him credit for questioning what the difference between Sylvanas and the Lich King really was by that point.
