When you look back at the air attacks on Yamato and Musashi, using literally hundreds of aircraft, it makes sense...but...can any one side muster enough aircraft to pull off something like that in the game, especially if they're dealing with fighters at the same time? We have to balance gameplay with historical relevance (notice I didn't say accuracy).
When you consider the number of dive bombers (Hornet, Enterprise, and Yorktown, VB-3,6, and 8) that attacked the Japanese fleet at Midway, you're only looking at 36 aircraft to sink three of the four carriers. Realistically, a couple of heavy fighters could wreak havoc on a CV, although I think CV losses are just as much a result of poor handling by the players as they are effective attacks by aircraft. CVs also have no form of damage control or repair, so once a CV is soft that's it.
Don't get me wrong, I like the idea, but there's other factors to consider when adding a unit with that much firepower to the game.
