I've seen this idea a few different times. It's really an awesome concept. Only time will tell, though. We'll have to wait and see what the full game holds for us. The beta was really limited in what was in it. Maybe weather will play a factor, but they didn't want to put it in the beta (either for server testing, secrecy, or other unknown reasons). Just gotta wait. But not a bad idea if we don't see this at first.
