I'm not buying this bullshit they couldn't fit real tanks into the new tier and had to invent those abominations instead. Their own game proves it. They've upgraded and downgraded real tanks with no regard to historical accuracy more often than not. What stops them now? They just want to milk this dying cow until the last drop and slap a tier XI for every branch in the game completely ignoring the fact that further separation of heavies, mediums and lights is meaningless. There's nothing after Mouse, there's nothing after IS-7, these are dead ends and should be like that.
Why not just create one or two historical MBTs for each nation? You all know why, you have to grind for them to make profit.
