1. Total War Weariness is a sum of the war weariness from individual wars. If you end your war with one nation, your war weariness with that nation will go down. However, since you're still at war with other nations your Total War Weariness may still increase. 2. Razing improves war score (which, in multiplayer, would be used to calculate the tourism/Aztec rewards for winning a war and the threshold for capitulation), but nothing else. War score has nothing to do with war weariness or warmongers penalties. 3.Nope. 4. Very, very slowly. I'm general, any time you gain war weariness from losing something, the person who inflicted that loss on you gains half of that war weariness themselves.
