Multiple versions of a race hurts race identity

I was thinking, if Blizzard goes through with Skyborne elves and then adds even more elf races down the line, like high elves or undead elves, it reminds me of one of my dislikes with retail. The original race starts to feel less unique.

I only play Horde so I don’t know how Night Elf mains feel about it, but having 3 different versions of elves makes each one feel a little less unique to me.

Same thing with something like Mechagnomes. I feel like adding another version of gnomes takes away a little from the people who chose to play the original gnomes.

I’d like Blizzard to avoid copying and pasting multiple races if it makes sense
