I looked up for the missile values and can tell that longbows have only small advantage in range compared to normal archers, which is historically very wrong; while standard bows could be effective and kill on distance up to some 90 meters (100 yards) the longbows made their kills up to more than 350 m (around 400 yards), their steel arrows piercing armor without much trouble. I am changing that and experimenting, for the sake of the game balance. I also know that the arquebusiers and muskets killed effectively in some 100-125 meters distance, but I was wondering what was the actual range of early ballistae, catapults, trebuchets, culverins, canons and mortars et cetera, so I could determine a proper ratio between those different units.
