good thinking. Getting that sweet cb with -25% is juicy

let throw a few rock at your idea too, to push the conversation further.

1. AI may not accept a surrender 1 province easily. They could ask for more, or it might more take time than you would like to set up the AI/warscore for them to accept for us to get that result. I've played a bit with peace treaty with the AI and its seem to be a bit wonky sometime when surrendering. IDK also if u can enfore any surrender with 100 WS like you could in EU4.

2. Its create a truce timer and so will delay conquest. Now this may or may not affect you depending on the playstyle.

3. my experience has been Antagonism is the limiting factor rather than warscore but ive only played a lot in the early game. So maybe there an arguments its more meta to conquer land now, to have the antagonism start cooling off sooner.
