Also the fact war exhaustion causes unrest makes no sense. We are tired of war, let's fight about it? It was more logical to me when it hit morale. I've not been a big fan of how rebels are handled in general and how it doesn't come in any other form other than a direct military problem rather than not paying taxes or even not being able to pay taxes if things got really bad but eh. I just feel the current system isn't a lot of fun at times and could be made something more in depth that has a variety of ways of dealing with it other than one.
For defensive wars i agree, but for offensive wars Its totally fine, that makes the most sense of all the unrest reasons in the whole game. Tax burdens increase, financial difficulties, shortage of food/equipment, sons & fathers die at the frontlines, etc etc.
