It’s just the same people spamming each thread again and again. Blizzard is just placating the vocal minority.
The Alliance already got a faction of high elves as a playable race. The void elves are high elves. Otherwise, they aren’t going to add the same race as a separate race to the Alliance. There is no cultural or visual distinction between blood elves and those choosing to continue to call themselves high elves. All of the allied races have at least some visual distinction and cultural backstory that makes them clearly distinct, and the allied races that are close to physically similar to another race (highmountain, lightforged) are on the same faction as their duplicates so it’s not a big deal.
At this point both sides have an equal number of elf classes, and even a class that can only be an elf. We’ve reached peak elf saturation.
