All historical matchmaking would do is swap Germany with Britain within “the big three” major nations. Doesn’t fix any of the core issues with nation balance as the tech gap between them would ruin hopes of other nations being viable ever. the BR system is the best concept there is, even if gaijin still has it far too compressed
Germany only stands a chance from 1942-44 because of tiger, panther and tiger 2 and then 1985 in a vacuum from leopard 2a4 amidst an army of abrams and strike eagles. Germany wasnt at the bleeding edge from late ww2 until very recently as it was occupied by NATO and USSR so was a mixture of sloppy seconds and working with whatever the british and americans let them tinker with. German wundewaffe is stupendously overhyped in comparison to what other major powers actually had in the 1900s, a lot of Wehraboos/Bundes-Boys forget that because they watched far too many “nazis totally were superior guysss” documentaries on the history channel.
Rest of the time its going to be the British, Americans, and soviets having absolute dominance over significant portions of years due to each of them creating vehicles which were generational leaps of technology at respective times of the cold war.
1948-1965 for britain because of centurion and chieftain with the constant fear of the IS3 and beyond. 1965-1980 for russia because of T-64 until abrams arrives. america from 1985 as F-15, F-14 and soon the F/A-18 own the air until 2008 as leopard 2 comes into its own and Eurofighter repossesses the skies from the US
Hardly touched on air, i think its pretty obvious that the US would dominate everywhere post 1949 other than a couple innovative british empire and soviet designs here and there until Eurofighter and rafale awaken and end the absolute dominance.
Naval… well thats Britain until about 1943 and then the USA makes everyone elses navy look like the local sea scouts dingy fleet. there was never any contest there
