Make PoBs an official faction only thing. Each official faction should have a right to have such an installation in a place prior discussed with a member of the devs or the administation in order to make sure the placement makes RP sense and afterwards, it should be pretty hard to destroy, but not impossible (equivalent to the current Core 5 PoB). The idea behind this proposal is making these bases a place where official factions can decide to place a station of their faction in lore without needing to completely rely on dev decisions. They need to be supplied and so on, with the exception of Nomad/Wild bases.
