I'd like more options for setting the scope of a war
I would like to see a more comprehensive war system to set the scope of a declared war, being able to press more than one claim per war declaration and have the option to press multiple types of claims simultaneously.
For example, as Emperor of the HRE, I'd like to be able to declare war on the Pomeranian leader seeking the following objectives:
1) Holy War On Pomerania for the Duchy of Pomerania
1a) Press De Jure claim on (County A in Duchy Pomerania) for (Vassal with a claim)
2) Holy War On Pomerania for the Duchy of Estonia
3) Press De Jure claim on (County B not in either of the Duchies already being claimed) for (Vassal with a claim)
The warscore for the war should be heavily weighted toward sieges taking place in the contested lands and major battles anywhere. Each claim should be evaluated separately in peace negotiations. In our example above, the war has been going mostly well, with several provinces occupied in Pomerania, including County A, as well as County B. In the peace agreement the AI offers:
1) HRE victory - gains occupied territories in Duchy of Pomerania, +100 prestige, +X MA%.
1a) ^^^ County A is occupied and goes to the vassal with a claim, +vassal opinion, etc.
2) White Peace/Inconclusive - Duchy of Estonia stays in hands of Pomerania, -50 prestige. -1 MA%
3) HRE victory - County B goes to vassal with a claim, +50 prestige
For AI decision-making purposes, each claim can be evaluated from its own warscore (occupations in that area + contribution of global victories), weighted sum determines total warscore. It'd also be nice to see the individual warscore for each claim.
So, it'd be easier to do enough to win a very small-scope war, for example fighting for a single county requiring *much* less accumulated warscore than trying to capture multiple duchies.
It'd also be cool to be able to declare war to force someone to give up their claim, or force them to transfer a vassal, etc.
Also, it'd be nice to be able to add additional claims in the middle of a war if it's going really well.
