... We do need beta-tester input on the "balance" of the AI, specifically if the escorts, DD and other smaller craft are too dumb, or at least in the ballpark with their reactions to your sub. We've more closely "tuned" the "CrewRating=" lines early in the war, that progress upwards towards a peak in early 1944, then declines slightly toward 1945. Traffic follows along similar lines, with more single and double groups of ships un-escorted early, with an ever increasing amount, skill-level and variety of escort vessels - at least, that's the intention. This is not to say that you won't encounter tough escorts early, just fewer of them, and smaller "convoys" - hopefully. Let us know what you think, as your career advances. Remember now, zig-zag can be ~your~ friend too!
