The guns are ok for acuracy , but you kind of have only 6 . And now with all the HE flying the large size and crap maneuvrability make the Izumo ANYTHING BUT TANKY . You are tanky only if enemy brings sub Yamato caliber battleship AP and only shoots it at you from your front ( and don't accidentally citadel hit your no2 barbette ) :P . Play it like a chicken and pray for a good team .
In my case it was the Colorado and stock Pensacola that killed the desire to play . I upgraded both with cash but the damage was done . Now i wait for a rebalance or something . I would congratulate WG for the carrier imbalance fix but unfortunately it came too late for me .
