I feel 2 or 3 of the outposts should be considered a no fire zone(spread a fair distance apart, corners of the map even). There are no mission givers at these outposts, they would provide a great avenue for social interactions. Shops can still be there and so will a new addition "a mysterious stranger" (maybe the one from the inn) who will rotate randomly through those islands every Friday (cough cough xur) and he could provide unique legendary exclusive items. this gives players a reason to go out and search for him/her and forced into the social spaces.
I think this would help get players into a bit more of a social mindset rather than kill kill kill kill kill kill (maybe loot) kill kill kill kill
