I find the current war support system to be rather frustrating. The same amount of war support is gained for winning battles, as is for capturing cities. I think the amount of war support for capturing cities should be much higher. On top of that, I think the war support gained from battles should be based on how many units were killed. I hate the fact that you can lose a war just because a lone scout or two on the opposite side of the map got killed while your main attacking force is still perfectly intact. Smaller armies should have a lower impact on war support than larger ones.

Capturing three cities should not give the same war support as killing 3 scouts. This is probably the most frustrating part of the game for me.

I'm trying to learn modding myself to try and implement this, but I wanted to get a conversation started about it in-case anyone else is able to do this quicker than I can.
