Well right.
I though have to disagree that it would be too helpful. If you want to do both - fight the orbiting defense and bombard the population then dont forget that ground installations tend to have quite many PDCs each. if you fight the defenses, the ground PDCs are open for fire, and then your shots just wont pass through. Same goes for when you just attack a planet. You can either bombard it by waves of seekers to get sure the neutron missiles get through the PDCs, but then again if you attack it with rockets you wont get anything from the bombardament.
