CV strikes are quite accurate often because of teammates threatening gun-fire angles and 'pinning' hostile ships to certain positions/angles. There is another aspect of Ranked play which impacts how a CV is played. In terms of 6v6 Ranked, CVs will typically interact with 2-3 ship Sub-Groups, so the AA interactions are actually fairly similar. Flanks usually break teams into halves and then ships tend to disperse out into sub-groups of 2 or 3 ships. That being said, it's very uncommon for a CV Driver to find themselves fighting against 11 enemy ships.

Ships are balanced for Random Battles as that is the primary game-mode for World of Warships.

Which leads to my question again, why are CV's allowed in 6v6? They haven't been allowed in the past several seasons of 7v7 CB's as well for reference. Simple question, why are CV's allowed in the 6v6 of Ranked? In this thread I linked below, himself mentioned how CV's are balanced around the 12v12 format (however balanced that may seem is another story), and that they over perform in smaller formats.
