And how did they "do Nightborne drty"?
Nightborne might quite possibly be the one allied race that got the most love and attention from Blizzard. Not only they are one of only two allied races (the other being Kul Tirans) who got their own unique model, while all others are just reskinned; but they also got their own player hub, the instanced Nighthold, as well. And they got so many new customization options in Shadowlands.
But even before SL, it was clear that the Nightborne were Blizzard's favourite allied races and the writers' pets. The facts do not lie. While all other Legion allied races were just reskins of existing models, Blizzard created an entirely new model from scratch for the Nightborne.
Storywise, the Nightborne leader Thalyssra was seen confronting Jaina Proudmoore, one of the most powerful mages in the franchise, in the Stormwind intro scenario. Thalyssra will also wed Thalassian regent Lor'themar Theron in an off-screen story. So even storywise the Nightborne got a lot of spotlight and attention from Blizzard in recent lore.
I do envy Nightborne players; truly, I do! I wish Blizzard would show to the Void elves and other allied races the same amount of sheer love and care they showed for the Nightborne.
