I don't even care about how Bolvar got squished, I'm more miffed about the hundreds of undead that got somehow destroyed off-screen. I mean might aswell just cut from start -> Bolvar kneeling, make the entire thing off-screen. What's the difference?
I mean Sylvanas is all gotta go fast but there were at least a hundred undead soldiers there, the hell did she do to kill them all?
