This. I’m not opposed to more customization options, but Blood Elves and Void Elves are already the most alike in physical appearance compared to any other two races in the game. Even Nightborne and Night Elves have more diversity between them.
If we give Velves more customization options, I think more “void” or dark hair colors would be appropriate (as well as a black and white color), maybe some more mismatching eyes or blind eyes, talons, void tattoos, or even additional eyeballs. But don’t give them Blood Elf stuff. That sucks for Blood Elf players.
