But everyone needs submarines... :(

Oh well, I don't play it anyways.

Well, there's really multiple problems with the implementation of submarines that I fully understand, one being in how you actually target and destroy them when they submerge. The second one is dealing primarily with the players of those subs, and in how slow the subs would be. You would almost never be able to get into the action compared to normal DDs, since the fastest U-Boat managed 16knts underwater. Subs would be cool, but would severely hamper development for the game.
