There is too much risk of this subject going overboard and then keelhauled into oblivion.
IF I had just three Nations then I must look at the big stuff I am effective in. American for the Georgia, Gearing, German for the Scharnhorst and Z52.
And one UBoat that I can live with at T10 having learned how to be dangerous with it to all near me. Keyword ALL applied in Satire. You do not want to be the teammate near me.
Here at this point the exercise fails. The rest of the other Nations are equally crappy. And the French and Soviet deadlocked for other reasons not part of the game itself. One of those two are going to be picked to meet the three Nations restrction.
The Italians are not part of the pictures. True to form, their ships are like their cars that rusted out in a couple of months. Its just as well that they have a strong diet of tomatoes, pasta and some of that cheese to get by until the meat load arrives in time for the big fat wedding.
Some Nations its easy to toss. Say the Japanese. The Destroyers do not survive dedicated gunboat hunters that delete them The Cruisers by design have too many workarounds and are just a Junker Car that has been bypassed so many times to run one more time... its a total failure. The battleships do not battle. ANY time you fire a Japanese BB guns, you get one wonderful OVER PEN x1. Guaranteed.
With all the Japanese Lethal Weapons of War are shown to be no good, everyone turns to one Johnny Socco, his wrist watch and a 500 ton robot that flies to pull the Chestnuts out of the fire.
The British might as well be dead before Lazarus gets to work anyway. Since they are always chopping stuff into cutrate sales packages too small to make a good filling meal...
The Dutch have lost their credibility by design months ago. To sit there and fire a dutch is to announce to the gaming world that you are now a official Cuck and cannot be bothered to defend your home and marriage from the bosche who loot and pillage you nightly.
The Asian Nations? Well, they all visited the Good will and bought out our mothballs. Slapped fresh paint into the ships and went to sea.
And the Commonwwealth? Well... If everything is equally crappy on that day of days the world over then its well that we do not noticed right away just how fooked we are as a Human Race. I know of first hand several warships sunk as a reef into the St Lawrence River because they cannot fight their way out of a yacht club.
