Oh you mean 350 pages of this thread full of the same people on both sides that can't back down? Sounds like another thread currently more active than this one
No one asks for anything "constantly" it's just the High Elf thing is highlighted right now due to getting Void Elves. I guarantee you if Void Elves weren't added there wouldn't be this much talk of High Elves that exploded after the fact.
Throughout the years of WoW High Elves have been a pretty frequent request, but it has come up that Horde players have asked for some Alliance races as well.
You can go ahead and read through this thread where the recent Alterac Human reddit thread was leaked.
I'm not gonna waste my time searching for evidence that's pretty easy to find and has been discussed to death.
And Blood Elves didn't reverse any effects, they just received a different magic source that doesn't require them to rely on Fel to feed their addiction.
If they were reversed they'd be reverting back to blue eyes and no mark of Fel would be a part of them. As it is, only Blood Elf Paladin and Priest NPCs will have the new Golden eyes, there will still be fel eyed Blood Elf NPCs because guess what? That's part of their people/culture.
