You cant compare Arty to CV Arty is alot more RNG.
And me myself i think CV at high tiers are too powerfull. They drop torpedos at an undodgeble range no matter what skill you have as BB player and there will always be 2 torpedos that hit if the CV player know how to drop em.. And with some high tier US torpedo bombers ive seen them hit all 6 torpedos on me when i was trying to avoid em when i saw the planes comming but they are so fast and can just get the perfect angle and range and still hit all torpedos no matter how i tried. How CVs are in the game is good i think but they are too powerfull and somehow they always easily end up on top of board.
From what ive seen is that Most CV players always have high average damage compared to other ships.. including myself.
I think CVs have a good role but they need some rebalancing. And if matchmaking balance fails, my prediction on win or loss is somehow always right when that happens.
