It’s just frustrating how many missed opportunities there were.
Particularly with Arathi. As of Legion the ruins of Stromgarde were occupied by an independent undead faction run by Galen Trollbane. Who you do ice in the DK questline but the point is clearly there’s no shortage of undead Stromgardians. The Black Bride is such a blank slate that you easily could’ve said she was Stromgardi. Perhaps even a protégé of Danath.
Trouble is then you’d have a situation where both the living and undead have completely valid claims. So the real villain of the piece is their mutual inability to coexist. And thatd make for a morally gray war story which clearly wasnt the plan.
Also if the Forsaken were actively trying to seize Stromgarde that would give the Alliance very good reason to commit serious resources to rebuilding Stromgarde. Khaz Modan would be living at gunpoint, obviously they cant have that.
Instead though it seems like the Alliance decided to rebuild this because of some Human reconquista plan. Which in itself isn’t the worst idea. But the story seems to be that they did that at the expense of aiding their Kaldorei allies in one of their darkest hours.
And again that in itself could also be a good story beat. But it’s the Alliance were talking about so not sending support wasn’t a problem, and Tyrande is told by her God to cool it with the righteous indignation shtick.
And as for the Forsaken we’ve zero idea how they felt about any of this. Belmont and Faranel escaped so clearly it didnt go catastrophically wrong for them. And the kicker is you could’ve done cool stuff with the Forsaken in Darkshore as well.
Shrouding a haunted forest in eternal night and burying people alive is sure to freak out most of the Horde. But you practically sent out a real estate listing add to the Forsaken. Could’ve had some “the dark is my home too” banter and even a counter to the Orc being buried alive scene with Forsaken bursting up out of the ground after burying themselves to set up an ambush.
