ya i avoid fights with DD's at all cost... its not worth it no matter how you look at it... if attacking a convoy i take them from the side, basic hit and run. I never seem to have trouble dodge'n DD's. If one does try and attack me I just go slow and dive up and down. If he drops on me I go all out and turn against him... but its best not to let him get close because they will kill you. So far im at 1943 and have only been depth charged twice.
