Change
The defender can chose the location to retreat to after losing a battle.
Reason for change
Currently, the attacker can choose which location a defending army retreats to, so the attacker doesn’t have to worry about the army retreating to a location more favorable to the defender. If a defending army can chose the location that they retreat to, then the attacker needs to spread out their army in order to prevent the defender from retreating to certain locations.
Playtest results of change
The change appears to reduce the incentive to concentrate troops in one location. However, further testing is necessary to see if the changes are enough.
