Maybe the more you spend, at a certain point, means the troops are better trained. Better trained means higher morale,
better attack and defense.

So maybe with pd 20, giants suck, but at pd 40, the militia are "well trained" and their attack defense and morale are raised by 2.

My original point, was that you only got improved pd if you spent points on it at set up. If your pretender did not buy improved pd, you are stuck with what you have now.
