Basically, we need a way to improve how Agressive expansion works.
Example would be this:
Suppose you are at war and got 60% war score. You contributed with 40% (and your war goal is something that would give AE), France with 20%. When Peace is asked, France demands, say, one province Worth 15% warscore and indemnities Worth 5%. If you gave them their demands in Peace, you would get 0% AE with them (from your goal) in that Peace deal. If you gave the province but not the ducats, 25%.
Why is that important? Because ot´s obvious that if you are fighting a common foe AND your ally got something he wouldn´t be pissed with you, quite the opposite.
