Wargamming just added in the latest patch the FV215b 183 (UK Tank destroyer), the new pay2win tank.
This think has a gun so powerfull that it can oneshot any tier 9 tank, most of the medium tanks and tank destroyers of tier 10. Only tier 10 theavy tanks can survive a shot from it's gun. This gun has been designed to work with premium ammo(works with standard too at half the performance) and it's the new milking cow for WG.
