I've never really been into the Alliance vs. Horde thing. I've played -- and have friends that play -- on both sides of the fence and I have fond memories of time as both Alliance and Horde. So why do the Alliance and Horde never seem to get along? As the game's storyline has pushed the Horde into the role of defacto villains, with Garrosh leading the charge to bomb Theramore, attack Ashenvale, and destroy the Vale of Eternal Blossoms, the rivalry's made a lot sense ... but it's also made me a lot less interested in playing Horde characters. (And I say this as someone who once had a blood elf main. Sure, blood elves weren't always good guys, but even my naaru-enslaving blood elf paladin had to look at Garrosh and say, "Hey, man, that's a step too far.")
But the expansions I've enjoyed the most have always been the ones where the Alliance and the Horde have faced a common enemy, pushing them together as at least impromptu allies. Even if we didn't always like each other, none of us liked Illidan or Arthas. The Garrosh-caused conflict in Mists always felt forced, like my character was being pushed in a direction I didn't approve of (having anything to do with Garrosh) without leaving me any options to decide what I wanted to do... it was go along with everything Garrosh wanted, or play Alliance. (Spoiler alert: these days, I play Alliance.)
So I'm actually kind of excited about Warlords of Draenor, since it looks like the entire game once again has a common enemy... even if it is still (sort of) Garrosh.
So what about you, readers? Do you want more war in your Warcraft? Or do you prefer it when we all work together? Do you think the factions will have to band together to defeat the Iron Horde?
