I think we need to make a drawing: Humans: variety of colors, variety of eye colors, variety of skins, variety of political views, thin and fat, still HUMANS. On a fantasy game, they (High/Blood Elves) just got their eyes changed by something that happened instead of being born with it, doesn't mean they are not the same.
But you have as well kultirans to show different humans.
So this being said, you can have repeated races, but i don't think it's necessary. That's all. They even made Kultirans large to differentiate from normal humans.
Why would blizz make players look to blood elves eyes or high elves eyes, to see who is who, unless, they change their appearance too?
They can change them.I will stay with @
Ignaz and say Nozdormu High elves personalization is the option here, no Doubt. They would look more unique. They got separated from Blood Elves so they can change meanwhile.
Maybe the Fel exposure didn't let Blood Elves evolve in appearance, but High Elves did. There is so much more stuff where you can have
creat(e)ivity and not just mess around with the information you have, lore wasn't made with existent things, lore was created with
creativity.
Being creative means someone that knows how to create. Not make a copy of a copy. And in this game you don't need to go in such a straight line.
(Even more them using void elves to show how we can just twist the lore in matter of seconds)
Nightborne will always be Night Elves variation. Evolved in a unique way, doesn't mean they are not night elves.
Night Elves evolved to Highborne and High elves, from Highborne to Nightborne, and High Elves to Blood Elves, from High/Blood to Void Elves.
Night Elves are like Human race, that had and have different people in every corner. It's ironic we being humans and not understanding there's different elves but they all came from the same first elves - Night Elves.
And the more they evolved, the more they appreciated other luxury than just nature, and living in trees. Seems pretty similar to humanity, in the beginning without much constructions there was a lot of nature, the more people appreciate architecture and loved luxury, the more that nature disappeared. But there's still places like those, for example, let's say Amazon. But they are trying to destroy amazon too. For what? To get wood, to make luxury toilet paper and paper in general. This is a luxury, i'm sure the nightborne would love it.
Dark trolls were the Australopithecus, and Night Elves are the genus Homo/Homo sapiens. (In evolution terms, not being racist, btw.)
My analogy:
All the elves are like humanity.
All elves exist.
None is dead.
