Holy shit the vid is making me belly laugh, oh wow. The biggest takeaway here is, Sylvanas being there, not killed. I wonder what they're talking about. Somehow I don't think I'll like it. Anyway, I'm so tired of using "Anduin" and "Sylvanas" in the same sentence.
Let me guess, Sylvanas and Anduin will go where no mortal has gone to find her true self or something equally bullshit.
Oh okay, discard that, I've just read the bit about it being a vision.
