At the risk of sounding like I was way too invested at the time, when I watched the Sylvanas Warbringers for the first time and had to process all it meant, I genuinely almost cried. It’s awful feeling so helpless about a story you care so deeply about.
I agree, both sides got a raw deal. The way to fix it is for Blizzard to build up both sides, not to tear them down. Let me explain.
It’s always more heartbreaking to lose something than it is satisfying to win something when it comes to WoW story developments. You’ll be hard-pressed to find nearly as many people celebrating the burning of Teldrassil as you saw people mourning its loss, outraged at the circumstances, or both. On the flip side, you’ll find far fewer Alliance players who were celebrating the Battle of Lordaeron than you’ll find Horde players mourning how horrifically the expansion has already started as far as Horde pride.
What I want is positive developments for both sides which don’t involve the destruction of the other side. Night elves get their lands back, more night elves get featured in more cinematics about night elves rather than just about the WotA or Highborne, maybe something happens with Elune’s intervention and the seed is planted (perhaps literally) for a new night elven capital to grow. Sylvanas doesn’t need to be forgiven, but she also doesn’t need to be killed or the Forsaken wiped off the face of the planet for good, satisfying things to happen for night elves.
For the undead, I’ll be honest, I won’t pretend to know what the best course would be for them. Their biggest appeal to me was always Sylvanas and her story, not to say I wouldn’t want good things for undead fans as a whole. I think it’s just hard for me to picture the undead without Sylvanas as their leader. It feels almost like if the night elves were expected to continue without Elune. Call it a cult of personality or whatever, but for good or ill Sylvanas was very deeply tied into their society as a representation of their unity through suffering. It kind of breaks my heart to realize Sylvanas will probably never be a part of that identity again. I’m sure other people have some good things in mind, who knows.
