Disclaimer: As a battleship main, and one that doesn’t play CV’s at all, I write this opinion purely from that of an observer to CV play and not that of an actual CV captain.
From my experience in the game since closed beta I can say that from the beginning the balance for CV’s has been skewed. To those who have put the effort into becoming a competent CV captain, I truly applaud (and at the same time loathe) you. It’s a ship class that I have tried but just do not have the patience for. That aside, the CV’s ability to move its weapons about the map with near impunity when top tier and to utterly devastate almost any ship when played by a competent player is frustrating and disheartening as a player. Unlike when against other ships where, if you make a mistake, paying for that mistake with a large amount, if not all of your HP is expected, with CV’s you can do everything right and still end up back in port if you are targeted by a good player.
