In order to make Oaklands more unique, I suggest adding unlocks (Maybe behind a paywall). Where you can choose to set up your base in another region such as desert/snow/acid etc, instead of everyone being around the shop.
This would also add reason to travel, and would fit themes of bases more, not to mention adding a layer of uniqueness behind your land.
With this, maybe a new building should be added near the shop or just add teleporters into the shop.. Or a purchasable item from the shop to put on your land that takes you inside others bases with no perms, or at least up to their sign. (So long as you have the area unlocked their base is in).
