My point on that is, it CAN and SHOULD be a national tree with national tanks - but it shouldnt be a greek subtree with leopard 2s in israeli which uses merkavas.
If your country really uses the copy+paste machines, then just apply the national decal to it - this won`t change a thing. And if there is a unique model, but its like there is only 5 greek tanks out there which arent copy+paste, then it should be those 5 tanks added to the developers of that tanks.
Because i chose to play the nation not to get “another t-55 and leopard 2a4” but rather to get its unique machinery.
And having said that, making main three “donors” to minor countries makes them irrelevant as trees, as you can get most of their techs in other countries, and those which you cant usually happen to be cacti.
and then we have that duality where ‘ones’ need and ‘others’ dont because applied different logic. YES, i agree, there are plenty and pretty of unique domestic machines, prototypes, ect ect in main nations. NO, they hardly count as ‘gameplay diversity’. Yes, im a big fond of the idea to keep trees unique, and no - i dont want to apply that logic only to those who ‘have many tanks’ and ‘dont need subtrees because main nations’.
I strongly believe that if you only have several unique machines, then they alone should be added to the producer/designer country to keep nations unique. And if you happened to have MANY unique models, as Korea does for example, then its okay to have own tree or subtree, based on the country`s history and\or ‘relationships’, or even straight up on game balance.
