I'd like any kind of change that enhances CV play. As a flight game CVs are very important and theres no bigger hoot then a CV close in accompanied by a hairy furball.
Which is why I quit upping level bombers to sink CVs. I would actually prefer seeing CV defense enhanced and/or make them more survivable.
Which is also why I keep getting shot to pieces running corsairs into heavily defended airfields to take out close by ords.
So that would be my question. How would new sea vessels enhance CV OPs? If they dont enhance them then why introduce them? This is, after all, a combat flight game. And there are certainly enough ways to sink CVs without adding submarines to the mix. Or BBs, or anything else that floats that will sink CVs quicker then they already are. We already have enough of a problem with these boneheads dive bombing heavy bombers like Lancs into our CVs.
We should dream up ways to make them last longer instead of how to sink them quicker. Thats what I think anyways.
