hm maybe there should be a differ betwen pasive(neutral and open for everyone) and aggressive (faktion locked or hostile to everyone) bases.
So that the peacefull *lets call it research and/or tradeing facility * still needs to be maintained but can not be harmed by players(admins still can use /kill ^^ )
and the aggressive can be blown up by everyone who has the firepower for it (and the needet rp if its above core1)
