doesn't mean it's bad or worth changing either.
like really as far as i can tell, most nations undersell their tech level in the game. we might as well give all majors all 1936 or below tanks etc if we're going for historicity. then there's likely more other techs to be sorted through. but basically most majors won't end up with anything to research that isn't ahead of time, if we don't have any open 1936 tech.
I think the lack of tech to research problem can be fixed if they add more specific plane and tank technology to give players big differences in quality, capability, and cost-saving quantity. Man the guns added a nice naval tech tree. There has to be more options than you can realistically get so a player has to make choices. I think they could do the same with tanks and planes.
Right now making better tanks or planes depends on the magical experience point resource...if you want more armor on a tank you need...xp...not more steel cost or research time? Very strange to me. A tank tech tree and deeper (and accurate) differences would really help here I think.
