But they’re not like… taking elements of Night Elves. Naga have been pretty clearly defined since their introduction. So while I’ll argue Nightborne are Night Elves forever, because they are… Naga are different.
But they would fit in. They were allies to Blood Elves after all and they’re as exiled as the others are.
I think a transformation to Scaly Night Elves like Worgens into Human would solve a lot of the issues with making Nagas playable.
WC3 is and will always be my primary reason for Nagas to be with Belves, Blizzard however just made a nice little lore avenue to pursue given the relationship between Belves and Nightborne and that Azshara isn’t dead.
