The Alliance in Warcraft was a diverse group of folks that teamed up for a common purpose that was more or less irrelevant around the start of World of Warcraft. Their leadership structure was primarily human guys are running the show with the help of the other races here and there. The Horde was a group of folks that were bonded together in struggle in order to ensure their own survival, lead by a messianic individual that lead them to the promised land basically. At least at the time of World of Warcraft's lore. From that standpoint, I'd say that the Exiles share far more of the lore traits of the Horde as of World of Warcraft. Bonded in struggle against an organization that has traditionally oppressed them, led by a figure to the promised land of Nexus. Given that the last race to be revealed on the Exile side may be zombies of some sort, and it's even more apropos. I'm not sure if one faction is going to be more favored than the other before seeing the other races to be honest. Unless something really strange happens, we might actually see a pretty even split of people in the factions. Exiles are the underdogs and have the fighting for survival vibe, with a couple bad ass races and a cute race, and the Dominion have the whole stylish overwhelming force vibe to them with some bad ass races. What they need to be careful of is something like how Star Wars the Old Republic was marketed. The Empire was portrayed as immensely powerful, totally cool, and they had an unstoppable Darth Vader type mascot who just wrecked everything in the promotional material, where the Republic wasn't really given anything that was cool in the promotional materials that I ever saw. Because of that, Empire was way more popular and their whole world PvP experiment became a huge joke. If Wildstar wants to have faction balance, they should hopefully have been paying attention. I think that they have as they've shown that both factions are equally funny and competent in their own way. I don't see anything like I did from Star Wars that made me think "man, everyone's gonna want to play empire in this game". Most of my friends that I've talked to are fairly split over which faction is "coolest" whereas for Star Wars everyone wanted to be Empire, so that's something at least.
