Need this feature as well as merchant ships to practice it on that if protected aid your nation's survivability, if sunk lower it. Railroads might feature into this as well. This would bring Ports into play more with perhaps a "light" airfield of a few Marine-use fighter choices, no bombers, available there.
Add a Recon/bomber floatplane like the many choices mentioned in the last years (Sunderland, PBY, H8K for flying boats; Maybe the Heron-Cant Z.506B Airone) and base these planes only at ports. Giving BBs and CAs floatplane catapults and one of the better known lighter floatplanes, say a Kingfisher or something, would also be sweet). The famous skip bomber, the B-25, isn't as necessary to gameplay just yet, but it would be a fine addition due to it's historical notoriety and widespread usage.
The other wish is that the game needs to have a graded victory/bombing scoring system like it does for the fighters. That is, succesful bombing runs by lighter bombers should be rewarded according to the difficulty of achieving that task with that plane. This would make lighter bombers worthwile rides.
Need a diversity of targets for the light-medium bombers that might include bridges or cover in tank towns.
If any new planes are needed after that, it should be skewed towards the early portion of the war in which the USSR is so poorly represented. So if I were to build a new plane, it would have to be say, the Mig or Lagg 3s and the Il-4. After that, I'd ask for Desert options--Gloster Glads, Falcos, Sm79s-81s, Ju52s.
If we need a hot plane, make it the Frank or the Tupolev. Surely we have enough 109s, Spits, and American Muscle to allow for new craft from another land?
He111 and Wellington, and Do217 next.
If an armored vehicle is offered after the T-34, I'd suggest one of the lighter tanks for a solid representation of early war armor. Perhaps a PzkwII or a Stuart (M5?). These would be most welcome in the TOD and CT actions. In CT, there would be those lovely old early war setups filled with Ostwinds, M16s and late model Panzers.
While many have asked for the Betty, I'd rather see the Ki-49. While not having the range or a larger payload, it was better armored and the Betty would be an instant Hangar queen and lend nothing to early war setups due it's insane vulnerability. I'd love to see it, but I'd model it only after about 15 other Japanese craft/vehicles were out.
