I think the issue with a lot of the issues with any future tech trees is the ground vehicles are there, but the air trees will be 90% copy paste. BeNeLux was almost at a level where it could have gotten a standalone tree and maybe Yugoslavia could, but I don’t think Switzerland or a lot of the tech tree suggestions could. I also think Gaijin is close to done adding new trees as the most recent 2 are some of the least popular and players are less incentivized to start new trees. I wouldn’t mind seeing a swiss tree but I think it’s unlikely
with the D.27, C-35, C-36, D 3800 (and all the subvariants) P-16 & N-20 there is still some uniqueness in the tech tree, but most of the rest would indeed be copy-paste
