The problem with the tier 9 and 10 is, is that now they are an only option. As far as I know, modifying those two are the only option. I am trying to think of ways to make them different that any us high tier battleship. Their one main feature I want them to have is that they can actually pull off a full broadside and not get killed in one shot from another ship. Unless the tier 10 from line 2 should be replaced by the tier 9 and 10 from line 3 and the line 3 tier 10 just connects to the line 2 tier 9.
