I enjoyed XI's conquest with signet, and hope at some point they bring something like that into the game. What I mean by something like that is, a type of system that really makes the player feel like they are effecting the world in a way, be it for the companies, cities, etc.

Does it need to be just like XI, no, as I'm interested in what the devs can come up with, but needless to say more content would be welcomed.
