I’ve got both Sweden and Germany to top tier in air, France, Britain and USSR to Jets
and I’d say yes there are some trees that Generally have a worse performance across the board compared to others
most of the reasons for a whole tree to be worse than others are weird mechanic changes like realshatter which benefits only Hispano and and Russian type 20mm guns
I’m talking in general, the system is horrible, we have events, battle pass, and pages of history 24/7, and the whole game is basically based around FOMO now.
