We are getting ear sliders on blood elves, and I assume the other elf races but havent seen confirmation, and the small option effectively adds half elf.
Ive learned to never say never, but I seriously doubt this will happen. See,s to me that these announced customization options are an attempt to end the high elf/half elf nonsense.
I get that everyone has a weird attachment to being a pale elf paladin on the good guy side, but unless they decide to throw lore in the trash and make void elves paladins I doubt jts ever happening.
