To add a Config variable for minimum number of players within a faction to activate homebase invulnerability. leave it turned OFF as default. Something simple as a deterrent for the "one man faction" and form a sort of empires at war feel if a server wishes
No.
There currently just are not enough controls where you could safely just invite any tom dick and harry and be sure you wont log in tomorrow to find your faction got assraped and they have left.
SO while you carefully look for trustable faction mates, you get targeted and pounded into oblivion because your base cant be defended, while everyone bigger can be?
Just because you have not yet found any faction mates worth trusting doesnt mean you shouldnt still work on building your station, building your fleet ships etc.
And even when you find 2 mates you can trust and work with, someone decides nah you have to have 9 mates or you dont count?
Bugger that, this is the internet, finding 9 people who arent dicks is hard.
There are other things you could do based on faction size but this basic thing is not one of them.
Either all have invulnerable main bases, or none do.
Not to mention, there are lots of valid one man shows going on.
Me, i mine and process resources, run my shops, lease out use of my ship yards, make and deliver drones etc for people.
Even sometimes do direct delivery of processed materials/components
Have public factories others can use to etc.
Not a huge need for a bunch of faction mates, not that anyone else would want to play that way either, but if my main base was not invulnerable i wouldnt be able to do any of that, player B would get mad i build fighters for player A and torch my shipyard, or some
one would decide to bomb the factories and storage areas and loot the place silly.
Then i would have to put big defensive guns everyplace, and set the game to be aggressive to all not tagged specifically friend and it would become a big ugly mess and i would be doing nothing but building big ass reactors to power big ass guns and loading the entire system up with them when i wasnt fighting anyone to begin with.
