Another thnig I have noticed is that Subs only target one ship at a time when atacking multiple ship convoys, generaly several ships were targeted with the bow tubs and sometimes even the stern tubs were brought to bear.
The damage text for the subs is also kinda wacky imo,Could it be alterd to say somthing like Floding or Batrie damage, somthing more in tune with damage a sub would take when being depth charged as aposed to that common to a surfice ship.
Also It would be neat if a B-1,B-2, or B-3 class sub were available once in a while for Japan.
Just food for thought, I love this game.
