I know the cruiser helped the Cv and all but im sure thats not all it did, YES it can help but as long as the enemy isnt swarming all of the fleet it migh as well be a turd floating in the water, the same hold true when the fleets get close and its time to use teh big guns, the carrier is then usless.
its like having to drive an airplane everywhere and then having to try to make a car fly, yes they can complement each other but they also have their own VERY differnet roles wich on will always burden the other. the way it is now is like ahving 1 big boat that does everything in a kinda toejamty half bellybutton way.
