I dont understand how some people argue on high elves and blood elves culture are the same thing. while their culture is as same as night elves and night born.
just like night elves and nightborn they were part of a bigger culture but they were separated. and having kultiran human and DI dwarf shows us that having different culture will end up with different racials.
just look at how different Aleria looks( tattoos and armors ) compared to a blood elf.
so high elves have different culture + different racials + different racial armor + difference in their character creating options (+plust point: different ideology).
void elves have these too, maybe even minus different culture and they became an allied race. so why cant high elves ?
