It's like talking to a wall.
Like, do you understand that High Elf also denotes a specific subsection of "high elves". That's why I prefer the term "thalassian" because people like you seem to be utterly unable to understand the difference between
high elf as the name of the the thalassian variant of elf, and High Elf, as a self denominational modern nomenclature that differentiates culturally and politically from blood elves.
As for the rest of your nonsense:
Regardless of playability, High Elf fantasy has been a part of the alliance since the beginning of WoW, and no matter how much you cover your ears and go "la la la" that fact still remains.
"Void Elf (Playable Race)" is simply the closes available model to play that existing fantasy, and the moment you understand that simple fact, you will be able to let go of your pettyness.
Me? I wish we had more hair colors so my High Elves looked more like they are supposed to, but I'm also so glad that my High Elves that were always meant to have blue hair get it. Because again, the player model and race is just whatever is closer to the fantasy of our characters, and my high elf mage looks exactly like he should, and your tantrums don't change that.
And those players that like the idea of their High Elves using void? so good for them!
Jealousy is a disease, so get well soon!
