The Tokugawa is too good against smaller caps because of its thin front profile. As replacing Vanilla ship models is undesirable (and rescaling, after having learned on some mistakes), removing a heavy slot should nerf it a bit. However, the ship was underpeforming against Bismarcks due to its much lower armour, making it unsuitable for charging, and due to the low number of heavy and medium slots that could fire backwards. Now the Tokugawa can fire the equal number of heavy turrets backwards as the Bismarck can forward. It can fire less prims, yes, but the Bismarck is a larger ship and easier to hit. I think the Liberty carrier should receive the same treatment.
