Since clearly there is not enough Copy-Paste vehicles in every tech tree, I propose another one. Rumania is getting the Abrams, so I only find it fair that the Italian tech tree gets the Abrams as well. Rumania is a part of the Italian tech tree, being featured heavily in premiums and also having the Osa SPAA at Rank VII, so it makes sense that Rumania would have a proper lineup for themselves with the Abrams.
While on subject of Rumania, they should get the F-16 with AIM 120Cs, Kub (Soviet SPAA), and maybe some more Russian tanks since Rumania used Soviet weaponry. Yeah, a tech tree folder T-72 (Rumania) with the Hungarian T-72, that is very logical.
