In humankind war support mechanic is great but if i compare in different games like multiplayer and single player.

 In multiplayer the player have an ability to make war competitive and can manage the war support mechanic.

In single player AI is not performing great many times AI become vassal without intense fight. I think that the war support need a minor change or making AI more aggressive.

The white peace seems to be useless in comparison to surrender.

There can be a change that every turn during war the war support decrease by 1 or 2. The speed can increase/decrease on winning or losing battles which will decrease war score so that player can only take its disputed area and have difficulty in making extra things or vassal. 

What are your views on it.
