You’ve gone out of order. Click and read the post. It first states:
The few referring to eyes, and skin tones.
Then, it’s stated:
Void elves will inherit the skin color options. That’s all it says. It does not say they’re getting blonde hair, or anything of the sort, and the “few customization options” are the eyes and skin in that order.
If Blizzard gives every single customization option to void elves that were intended for “core races only” as we were told, the player base will have a bigger fit than it is now and the entire identity of blood elves and void elves will be entirely trashed.
