Just play 8.0 from Alliance perspective. You lose or your early victories are tainted. Seriously, all of BfA feels like what you're describing; NPCs are dying, the world is going to hell, and we're too busy fighting one another to save a freaking planet. But then it's also WoW, so when things get really bad, we just open a ton of portals to all different places, hop through one, and find a new home somewhere else.
