that’s one point i think you can pull as a good idea. like markets, your reach is restricted by your region. it allows for an entity with a defensive deficiency or other groups to form a staging area where the pressure is off.
the only real effect that might be game changing might just be that the common warganking entity can only restrict access to one trade hub at a time unless they split up. and if they don’t, might just drive more business out to another area of space.
