I’d be much more interested in playing a Nightborne if they had that “nightfallen” look available. As it stands, they’re just another generic elf in a sea of generic elves. They’re boring at best.
Honestly, having the whole race “stuck” at the nightfallen stage would have been a much more interesting story. Yes, they’re free of their tyrannical queen, but at what cost? Conflict is at the heart of any good story, and by curing them, there’s no conflict left.
Imagine if they had a racial passive that gave them a small buff whenever they took magic damage. Nightborne players would keep dipping into magic attacks to get their buff, like the magic addicts the characters would supposedly be. Gameplay and story working together, madness.
Anyway, it’s a moot point. At absolute best, Blizzard would crank out some half-baked cosmetic skins and a 15 minute questline that made almost no sense. Right, red draenei?
