i think they'll be like in old UO - for example, at some point on certain servers orcs invaded the town of cove. You could go there and fight them back (killing a certain number/pushing them back, until the next more powerful wave came, then doing it again) or go around looting bodies, or killing other players there, or not going there at all. The players decisions dictated the outcome, but at no point did you go somewhere and accept a quest, you had no journal message telling you "You must kill 9 more orcs," the only experience you got was for killing orcs/players, and the items you got from the bodies - and maybe a reward at the end to a handful of key players. Afterwards, the orcs were pushed out of cove and guards once again took control over the town.
