As per my opinion right now CVs are extremely OP especially in ranked/random battles. I tried to compare dmg done with HE shells from COSSACK to VLADIVOSTOK and to GRAF ZEPPELIN - 39 hits to both ships. Dammage done to VLADIVOSTOK - 6416, dammage done to GRAFF ZEPPELIN - 1422. In the same moment GRAF ZEPPELIN did 35 shells from his secondaries to COSSACK for 11 889 and 5 rockets for 6112. How comes BBs with very thick shell getting more dmg then CVs with less thickness, main guns of DDs making 9.5 ( almost 10 ) times less dmg then secondaries of CVs. Also CV dammaged two of my modules (turnets and torpedo tubes) even my commander trained PM. This incapacitated my ship and there was no chance to sink him. In the same moment you can not prevent CV to rise planes or completely to dmg secondarioes. If this is not OP ships I don't know what is OP then. To ballance game CVs shuld be more vulnarable, to making less dmg especially to DDs and range of plans to be restricted for example around 20 km from mother vessel.
