Well, water would just be another "upkeep", its not really a goal. - I'm a fan of hardcore mode, so its not that I don't like the idea. - A goal in that area would more be to control a reservoir, or water caravan, or something like that.
A goal would be more like: Become the highest rank in the BoS (or any other faction) or capture and control X for BoS (or any other faction).
