I can see where this could get ugly real fast lol.. Since I didn't want to break my game or have large warships sinking from me throwing a rock at them, I just took all of the torpedo values and increased them by 10%-25% somewhat arbitrarily. I did the same for some of the shells.
I have no idea how this is going to work
.
Usually once I start messing with settings like this things get out of hand and I end up reverting back to original game/mods... life is sometimes simpler then
