Just a few points, regarding the upcoming 8.7 changes. You'll like them :)

- T-50 will NOT apparently lead to MT-25, it will lead to T-34

- MT-25 will be unlockable from KV-1S

- current accumulated T-50 XP will be somehow transferred to KV-1S

- Panther tanks (apparently both Panther I and II) will be rebalanced, they will lose their top engines, but will recieve a rate of fire buff (amongst other things)
