Besieged was an "event" in FFXI where the town was raided by Beastmen and depending on the outcome, certain NPCs would be captured that had to be rescued... including vendors that sold exclusive stuff. Town (or outskirts of Town) Besieged-esque FATEs that brought more immersion into the game would be a welcome feature for which I am certain many folks would enjoy. Perhaps area reputation ranks could be attained for rescuing/participating in the events, rewards to include lowering vendor items costs and/or providing access to new items at shops.
