I agree, but I feel that there is a gendered element to it still? I mean, even though characters like Thrall, Varian and Garrosh are being handled just as badly, they're still given weight in the plot. They're important, and it directly impacts the story. The women you mention, on the other hand, get paraded onstage to do their song and dance, but when the curtain closes it means nothing. Blizz went overboard building up how Jaina would So Totally Snap and Get Involved, but her rage in TOW was... curbed. She got mad, and then was given a man and a title to calm her down. (Although hopefully her actions re: Sunreavers will actually mean something.) Tyrande gets hauled out after gathering dust so long to... make a mistake that leaves no effect on anything, ever. She wasn't given any agency. Her actions, and their consequences, were completely negated by Varian's Big Hero Man Presence.
Not really. Garrosh is being made to take the fall as a giveaway to the Alliance, which is nice I guess in the "I'm glad that you noticed us" kind of way, but it doesn't get to the issues that we were complaining about in the future.
Thrall, Tirion, Malfurion, Varian, and Raynor (Yes, I'm throwing him in, as I said, this is a systemic problem) all suffer for different reasons though. They're world characters (with the exception of one, but he still has the same characteristics), they're always supposed to be right, super powerful, super smart, and generally "awesome", and Blizzard tries to show this by making their opponents and their friends look like idiots. Disagreements with them usually end with the revelation that the complainer was evil or stupid, and we move on without any sort of argument.
They all feel like author inserts as well, with the exception of Malfurion. Many of these characters are really the same character with a different coat of paint, and they displace what's going on with everything else in the story. Given what we know about Thrall, it wouldn't surprise me.
The displacement is the issue though. Just about every other character suffers as a result of being in the same scene as the world character, and this needs to stop.
