There weren't only task forces. Ther could be landing forces, cruiser groups, sub groups, sub hunting groups,and light carrier groups. Wouldn't it be easier to have a landing force with a light carrier, destroyers, and launch vehicles plus have support from another carrier? How about light carriers only fit certain types of planes. Cruiser groups could be cruisers, one battlecruiser, with only one battleship and launch vehicles. Sub groups can be a wolfpack of subs that can launch player-controlled midget-subs. Sub hunting groups perhaps can launch sub-hunting planes (floats), corvettes and can be a group of destroyers. Light carrier groups can be a light carrier protected by destroyers and follow a carrier. But, they all can set their own course. In the end it might be complicated.
