All that Hitman has mentioned is true. Everybody who plays a subsim has a learning curve especially beginners. You develop your own tactics for attacking and then escaping. Sinking the destroyers first might work, but expending torpedoes on a DD which might take one hit and sink or it might require more and later you might see a nice big fate tanker come along that you could have used those torpedoes on instead of the destroyers.
In the Pacific war there actually was a president for sinking destroyers. It was late in the war, mid 1944. Just before the Battle of the Philippine Sea. The Silent Service had a priority list with which certain ships would be sunk first instead of other. Japanese capital ships were always high on that list. Tankers were another high priority target. Japanese destroyers were moved to the top of the list in mid '44 because of the destroyer shortage that the Imperial Navy experienced during that period.
