Revolution

Could you be more detailed as to what a revolution would entail? The game already has revolts/rebellions which can cause provinces to change loyalty to another nation.

I mean so it can like make it's own country named after the province and they would use your supplies to attack you and some troops from your army can revolt against you

They would almost die immediately though when they're alone, so unless you have multiple provinces bordering each other that would normally rebel, they should go to another player so they can be protected by somebody who may be more capable than themselves. And even if you have a large number of provinces together about to rebel, they would have little to no units and you could easily steamroll right back over them.

It might be interesting, slightly, but no more than a slight irritation.

1 militia unit, for example, can be crushed by most any decent army.

Most peoples morale is decent, so that wouldn't happen in too many situations.

imagine having 1 province rebel and become independent. that country would be instantly crushed by other forces. this isn't the American Revolution where the US had 13 provinces rebel and were able to fight it out. not to mention, the CoW staff would have to come up with a list of possible country names. a job I am 80% sure they do not want to spend time on
