Hear me out. I think subs should not be able to get shot while submerged because they are already weak as and they already have huge disadvantages. Also realistically a shell would more likely bounce off the surface of the water hence why I think that it would be better if submarines can’t take damage from main guns while submerged. They also have hardly any health. Make it fair for the submarines. Even if you make it so that they can dive deeper so they can avoid the damage from the main guns that would be great.
