Tell me, how are you going to clear a village that has 80k spears swords and archers and a bunch of HC in defense with only 300 rams in your nuke? Not. You will need spearhead nukes. You will need the cannonfodder to make sure your regular nukes that follow can kill more troops. In this stage, troop ratio's make the difference between having 50%-80% of the troops in your nuke dying. In later stages, it makes the difference between using 6 nukes and using 10 nukes to clear a village.
