Would like to see a firebombing raider whose AI goal is to set walls (not buildings, a building has a roof) on fire/blow them up... start including him after the second cycle, and he will start attacking any wall in a fairly large radius while the raiders are in the planning mode... thus it will look much more like they ARE planning/preparing to attack, by weakening your outer defenses.
This also answers the tactic that people choose to take by building walls in the wilderness to funnel the raiders into a kill box, that alone would make raiders much more dynamic.
