Thats what I meant about the size of the team. If it's really small, it'll be hard to implement it. Unless they can put a sorta like "future-anticipated-storyline" sort of thing into present patches. What I mean is that there can be choices in the middle of lore-changing quests and depending on the choices made the dialog and target may change. I know that devs keep logs of players (for those of you who are reported for naughty thing >>), so if they can compile it into a survey system, they just need to check up on which choices hit the most (or if there are some which are about even), then change future events accordingly (as like which armies or countries or worlds, in this sense, win and get territories or something). Well, in the end, its still a big strain on the manpower factor here so it might not be feasible even with a choice-survey-system.
P.S. making up terms here xD
