I have to agree that this system brushes up against greatness, but would do better to allow more granularity in CAG construction and if a mission applies to the whole CAG or just parts of it. The big problem with the system as described is that it cannot replicate some of the reasons behind the US victory at Midway. Planes equipped with the wrong bombs, the carrier runways tied up by the need to land returning aircraft, and the cat-and-mouse game of what you choose to strike with and what you choose to leave in reserve. As Midway showed, there is a big difference between having aircraft on a carrier ready to strike a land target and ready to strike a naval target and making the wrong decision can cause major problems. Sure this is somewhat covered by having the whole CAG group assigned to one mission and have it be the wrong one, but I think that concept misses out on a potentially better way.
If I understand the system as presented correctly, players have an all or nothing choice: strike with the whole CAG and leave the carrier undefended or focus on defending the carrier and not be able to strike at all, except at the opposition's CAGs which may or may not be striking. Imagine a scenario where both parties decide to focus on defense and a carrier naval battle occurs without anyone launching any planes. In such a case I think you've created more micromanagement, not less, by forcing the player to constantly change the mission of his entire CAG group as the situation changes rather than giving orders to 1/2 to stay behind and defend the carrier and 1/2 to strike and potentially return focus to say, the massive land battles raging on the Eastern front. And I think you're somewhat needlessly losing the ability to follow your mantra for this game and give more control to the players, if they want it. Just mimic what you're already doing with other units where composition is something that has defaults, but that the player can monkey around with if they want.
This is all from a player who doesn't like micromanagement and never got into Vicky--the way described would, I think, give me more micro headaches than giving me the ability to fine tune my CAG composition and orders before engagements and not have to worry that every hour I'm not watching what is going on I'm blowing the whole battle by not switching around naval attack order to defend.
