I'm fairly new, so forgive me if this is stupid or has been requested before. I think it would be awesome to have battlegroup vs battlegroup maps, even in the MA.
Each side gets fleets instead of airbases. We'd need new ship models though, it would be nice to have a few more US models with the addition of Japan, Germany, UK, maybe even Italy and France.
I think it would be awesome. We could have light fleets with Independance/Taiyo class light carriers, with light escort, and main battlefleets with several Essex/Illustrious/Shokaku class carriers. We'd need maybe a battleship or two. Nagato/North Carolina...though I have a soft spot for Nevada class . Be neat to have a Kinugasa cruiser for the Japanese fleet, and a light cruier in the mix, Brooklyn Class for the Americans.
Also like to see the ability to use the main guns on our destroyers and catapult launched aircraft. And...dare I say it...the PBY Catalina. Ok ok, yes I'm a geek.
Hmm...make this an expansion and sell it to me at a reasonable price. I'll buy it.

And this has been bothering me for awhile......why no P39 Airacobra? As far as ground attack, that's always been my favorite.
