This line is average overall.
From level 4 to level 9, they are all pretty bad. Only Christopher Columbus at level 10 is stronger. Let’s not talk about levels 4 to 5. The ships below level 6 in World of Warships are all very bad, so there is no need to introduce them. Level 6 Andrea Doria is a standard Iron Bastard, with weak firepower but strong protection. Levels 7 and 8 are relatively average. They have some attributes in every aspect but are not strong. They are at the level of a bastard. The ninth-level Lepanto is better. The 3×4 main gun has made a qualitative leap. It has a certain ability to suppress destroyers and cruisers, and it belongs to the T2 level.
The main gun of Level 10 Columbus is upgraded to a 4×4. Although the caliber remains the same, the damage is higher. There are no shortcomings except for the poor walking. The summary is that this line is only playable by Level 10, and the rest are very average.
