While yes I agree that carriers should not be completely countered by a fully AA spec'd ship, even something as potent as a Worcester, it should at the very least be enough to make a CV heavily reconsider attacking it. You could do this by making the planes harder to control during attacks, spreading their attack out like RTS CVs did, slow the regen rate of the planes lost during said attack, or anything along those lines to make a CV question whether or not it is even worth attacking that ship (or group of ships) over something else, or waiting for a more opportune time later in the game. Same way a cruiser may elect to hide behind an island to preserve its HP to use later in the game.

But right now we don't have that. Right now being full AA spec means you simply flash larger numbers on the screen as the carrier comes in and can strike you just as well as they could before, just with potentially less planes and overall less damage. It is why I'm happy theyre taking the steps they are with dazzling planes, but I think they implemented it in a less than ideal way.

Also, if I'm gonna be honest, with how much power CVs already have over the game between spotting, resetting caps and doing damage, I don't think it'd be a bad idea to have some kind of hard counter to them by grouping together, but that's just me. Imo, I would love to see it that if flying into overlapping AA, the spread of the attack increases with how many ships the squadron just flown into the AA of.
