With so many Bug Reports piling up and players unhappy with the state of their top tier vehicles, I want to urge Gaijin to please consider delaying a tech tree update to focus on Bug Reports! Its really unfair that only a handful of vehicles get Spall Liners considering how effective they are at increasing survivability in War Thunder.
You could even prepare some low effort premium vehicles for every nation worked on so people can show their support for fixing top tier vehicles and continue funding the work.
If you really wanted to add vehicles, you could focus on filling tech tree gaps with low effort copy paste vehicles.
BR changes could also be some additional lower effort work to add more meat to the update. A lot of issues with vehicles can be solved with continued BR decompression and fine tuning. It would be an easy way to score points with the community.
