Ever since I first looked at my character's skill list (almost six years ago now) and saw there was actually a skill bar for languages, I have had an idea planted in my head. If my character has the technical ability to learn languages in WoW, why couldn't I choose to learn Orcish? This notion led me further to ask, "Why can't I be in a cross-faction guild consisting of both Alliance and Horde races, working together to accomplish great deeds?" When I relayed this idea to my guildies at the time, one guy actually told me it was the stupidest idea he'd ever heard. Really?
There has always been precedent in the game for this kind of cross-faction cooperation. We can see it in groups like the Argent Dawn and the Cenarion Circle. Hell -- even the Twilight's Hammer is more racially progressive than the Horde or Alliance. And don't even get me started on that racist jerk Varian Wrynn. Oh, I know he was mistreated in captivity by orcs, but his mistreatment is nothing compared to what Thrall endured at the hands of humans, and Thrall's first instinct has always been of peaceful resolution rather than conflict (and for reference, I'm an Alliance player, folks).
