As the name implies, nullsec has very high security and not very much emergent gameplay.
I suggest we up the amount of NPC Sotiyos to 10 per nullsec system and everyone who undocks or un-tetheres will be instantly annihilated just like in highsec.
The NPCs guarding those Sotiyos are quite capable and should be able to annihilate all ratting sooper dooper doopers quite easily and if you want to get rid of them, you can “just shoot them”.
For NPC nullsec I suggest the number of active NPC Sotiyos at one at any given time.
This will bring lots of involuntary dis-assemblies of capitals all over New Eden and will make nullsec a very emergent area to live in.
Nowhere is safe in New Eden, better be on your toes in nullsec.
