Only 1 problem. Humanity never betrayed the Elves. The high Elves are still Alliance, just not a playable race yet. And the argument that the Blood Elves were betrayed because Arthas went in and destroyed the Sunwell has the convenience of forgetting that he destroyed Lordareon first. The Alliance never betrayed them. I doubt Blizz will ever bring Alleria into the game because if they do, well, that makes things hard. She hates the horde because of their atrocities and is fiercely alliance, however Silvermoon would immediately recognize her as rightful leader. As for humanity betraying the forsaken, actually they didn't. The forsaken was created by the Legion as a way to destroy Azeroth. These undead called forsaken somehow were able to shake off the mind control, but it's still asking a lot of people to ignore people who were made to kill you.

The alliance did betray the blood elves: they basicly left kaelthas and his followers to die against overwhelming odds by taking most of his troops (WC3 frozen throne) and the alliance leader showed his racist mindset. Then when kael thas did the only thing he could do: ally himself with the nagas he was imprisoned and sentenced to death for treason.

Lilkitten: The Alliance definitely betrayed the blood elves. The entire blood elf campaign in WC3 was tailored to show how they were systematically disenfranchised by the Alliance and the incredibly racist Garithos. The remaining high elves account for, as I recall, 1/100th of their original population. The rest were either killed during the invasion or became blood elves afterwards.

Also, your facts regarding the Forsaken are simply wrong. You're confusing them with the Scourge. Arthas, Prince of Lordaeron, slaughetered his own people, and THOSE are the Forsaken. They're the citizens of Lordaeron who were killed by their King but regained their free will. They were subsequently deemed monsters by the rest of the Alliance and joined the Horde.

The old Lordaeron / Silvermoon alliance between humans and high elves lives on in present WoW as the alliance between the Forsaken and blood elves. This was even confirmed with in-game text when BC came out, and the Forsaken commoners were saying things like, "Ah, fighting alongside the elves again, just like old times!"

I guess I should mention I'm Alaska Native. That's why I'm biased against Alliance for representing Western culture and their intolerance, minus the Night Elves of course. Suzaku did make good points supporting me though, thanks. I also wanted to mention that, as I understand it, the Night Elves banished the High Elves/Blood Elves in the lore preceding the Warcraft games.
