I think we should be able to attack ships in our zone of control or atleast be able to contact other player to remove their rust buckets off our ZOC without inciting a war.
Also I think Starbases should be free gain as in you should have the right to attack them if they're not in their zone of control without inciting a war.
Also starbases shouldn't give ZOC unless they have influence upgrades.
We have "open borders" agreement for that kind of **** but right now it's not used for anything.
