World of Tanks Console - BT-SV following the Buff/Nerf October 2024.

They have nerfed the chassis rotation, and to me, this makes the tank difficult to enjoy.
The vision range has been improved, but in battles like this one, with many Tier IV present, you don't make much difference as a light tank.
I was mainly playing the BT-SV to get some assist damage.
Obviously, the allies had to cap when there was only one tank remaining. And as you have also observed, it is always those that have contributed the least to winning the battle that are going to cap.
The BT-SV can be fun if not facing Tier IV tanks; but it seems that after this season's update, Tier III are most of the time in Tier IV battles where they have very little impact. The only tank that can hold its own with any Tier IV is the UE-57. But it is a difficult tank to play.
