Guild based vs faction based

[Hoofhurr]

Yeah I'm not in favor of declarations either (you make a choice as you make your character practically). Still I'm worried that while this sounds fun to create, once players align themselves with a faction and do everything they can to move that faction forward, aren't all the choices they make sort of defaulted? Where are the difficult and interesting choices players have to make? Where are the trade-offs 3-4 weeks into the game?

As a player making a character you decide before you take your first action which faction you want to be a part of. If that's going to be important to the game how do you make it interesting to sometimes have to make choices against what you personally decided early on?
