Recently I touched this too. From the changelog:
- Decreased civs general willingness to target far-away independent cities
- Vassal civs are set to never target indy and barb cities outside their war maps
Will see how much does it improve on the current situation.
In related news, I'm now finalizing the changes in the update.
Will be up tomorrow.
Maybe tonight, if I manage to stay awake for a couple more hours. Wouldn't bet on that though
1.6 version started now??? Excellent!Bravo!
