Rather to fix a current issue. The GM should look into fixing War protection. Maybe so its an all empire or no nation fix. I vote 1GC per Day per nation. Make alot of issues simpler.
And i would like to suggest that in order to dec a nation must be atleast 30M population. This means players must invest something before attacking anyone. And atleast they get a pop with pop/worker trades. Figured it something to increase the risk
