Warcraft 3 had the remaining Orcs fleeing across the ocean to escape the Legion while the northern Alliance kingdoms were annihilated by the Scourge. Ultimately Jaina and Thrall's forces joined up with the Night Elves to destroy Archimonde, of course.
And then in the expansion, the "Human" campaign was actually Blood Elves and Naga, and there wasn't even a proper Orc campaign. Just an RPG-like set of maps that were added later and all took place local to Durotar.
This whole discussion over who is "favored" is stupid. The story has ups and downs for both factions and it isn't supposed to be equal all the time, nor should it be. That would be totally boring.
