It's a shame you and your friend choose different cities. But there were plenty of warnings that new items and drops would come from each city etc. and to not pick one based on the current rewards. Besides, once we get jobs and time goes by, maybe the very city you are both in now IS the city you want to fight for.

I think that it is a GOOD thing people can't change their Guild Company. We need some pride/competition events and game play added to this game and these companies are one way to do it. Guild Companies might even be a way of building friendships and creating teamwork between people who would otherwise never meet in game. Also good.

If and it's a BIG If, they ever allowed for a guild company change it should be one HECKA quest to betray your current city to join the ranks of the other. After all, who wants a traitor on their team :P

This being said: I wouldn't expect being able to change companies until sometime WAYYY after 2.0 comes out. However, in time yes, it will probably be added. But it's not something as simple as letting you swap companies by answering a couple menus. If it was, we'd all think 'boy, that was lame.' Properly setting it up that we can switch guild companies will require quests, storylines, punishments etc. that all take time to plan, create, write, localize, test, etc. ...time SE is spending doing other, more important things. (Again, they warned us MANY times Company Choice is forever)
