I have played through a games so far and Athena has done the same foolish thing many times and I am wondering if there is a setting that would make this behavior rare. Specifically, Athena often hunkers down inside cities or redoubts and then just waits. If you sit long enough outside with an army besieging the city they will eventually surrender during the siege.
Is there a setting or difficulty level that makes this behavior unlikely? Parking the Army of N VA in Richmond with RE Lee and letting it sit there until is surrenders in siege is foolish.
