Lore (new and retconed) aside - in my opinion nightelves have the most coherensive social cultural background of all races in wow.
The art, the story, the druidism, celtic symbols, the abandonment of arcane magic, this whole treehugger pocahontas middle earth mix, is just perfect.
Taurens on the other hand, are FOR ME (!!!), not for everyone, just cows that dress up like indians.
Indians never had druids! They have shamans! And that is the point where some might feel "Meh, this does not fit".
