The game is actually shaping up pretty good now with all the mods. In terms of what I think would need to be adressed:
1. reworked 1939-43 campaign, along the line of RSRDC in sh4 with historical quantity and type of ships. I understand Magnum was interested, but this requires a whole team.
2. additional ships. I understand Privateer, Iambecomelife and others are working on that.
3. dud torpedoes: early war german torpedoes (39-42) had many of the same issues as american ones, but none of that is modeled in the game;
4. wet weather gear for deck crew. Not essential, but would be nice;
5. Crew management is actually not bad in the campaign with the "no magic skills" mod, now that the morale issue has been fixed, although there are still issues (ranks, skills) that need to be addressed;
