I wouldn't get rid fof the deckgun either.... I like to take a chance and tempt fate every once in awhile.
I would however like to see a mod for increasing the number of shells for the deckgun. I really only use the it if I'm out of torpedos and have the need to sink that last couple of damaged ships that are sitting there not moving, and won't sink. Ramming them sure doesn't work, as I've even tried that as a last resort.
I've tried every which way to increase the number for AP and He to at least 20 over the stock game, but with no success. Yes I've read how before but it's not working for me.
