Well your classing for cruiser/dassies is false...there are Light destroyers(kusary and i think this one is alone in its class) and meadium to heavy ones(corvo/storta/ai cruiser - as to my knowledge there is no heavy dasies because that a light cruiser) some ships are refered ingame as cruisers but theyr not...a destroyer is very agille while a cruiser in its true meaning is a bombarding platform that lacks agility but has enaugh firepower and armor to compensate that and the battlecruisers are a more heavier version of the heavy cruisers
