Airplanes:
Airplane operational radius is too small. On large complete world maps, it would take a number of moves, and many airfields to get them from one continent to the other. I checked max range of the beechcraft Tac bomber, its 1.078 km.
According to Google earth Ruler, that is a flight range from Tripoli - Libya, to Rome - Italy.
According to this game, the flight range is ~200 km ( assuming it ).
Proposal #1: Please increase airplane max flight range.
Planes:
If the problem is people abusing airplanes, well Anti air should be made either cheaper, faster to build, or Added to a province with a fort upgrade. Ranges of planes are too minuscule to be considered effective.
Proposal #2: Convoy defense at sea should be bear minimum.
Submarines:
Submarines take serious damage when attacking convoys. It should not be the case, since submarines could easily destroy a convoy unit. ( Atleast in the real world ).
I had 2 submarines stacked attack a convoy of soldiers, at half morale, and lost 1 submarine
Convoys were especially vulnerable to Uboats at the start of ww2. Most of them were unarmed shipping haulers from the west heading to Britain. While Uboats were somewhat also primitive, they had a good Kill death ratio.
Convoys were no threat, until destroyers were sent on convoy escort missions, and until convoys were armed with better firepower. I am basing this suggestion on such, as this game seems to revolve around 1936, with tech trees starting at 1936, and find it strange that convoys actually do quite some damage to submarines, which, basically should be no match for Convoy ships. ie : 2 subs vs 1 convoy, result is 50% morale drop.
Submarines in Supremacy1914 / can be according to many, doubtful to cause or be of much use in open seas, However, improved Uboats of ww2, were as effective as the state of the sea - i believe.
They are powerful units in their own right and should not be considered as weak units in my honest opinion. ( Low level subs specifically - even higher tech subs, in my opinion would be just as good as Battleships ).
Optional suggestion: Please also consider extending the info panel on unit specifications, specifically firing ranges. - Artillery and rail guns on construction menu.
