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
T-50下一级的车不是MT-25(T-50-2的替换车)，而是T-34

– MT-25 will be unlockable from KV-1S
MT-25将从KV-1S点亮

– current accumulated T-50 XP will be somehow transferred to KV-1S
目前在T-50上的经验，将以某种方式转到KV-1S上

– 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)
黑豹(黑豹I和黑豹II)将被重新平衡，会移除他们的顶级花冻鸡，不过会得到射速上的增强
—顺便测透细节:——

It won’t lose it’s top engine it will be reduced to historical output of 700HP. Panther II on the other hand…It’s quite possible they will remove the top engine
黑豹I的顶级花冻鸡是砍到700马力，黑豹II则有可能直接砍掉顶级花冻鸡…
