At the moment the experience of playing tier 8-10 is dictated by how many tds (high alpha tanks ) are in the mm. I could play the game and end up with only having 3 tanks on the enemy that can remove a 1/3 of hp and it's a fun experience but other times it can be 7+ and just makes the game unplayable.
The Devs have shown the don't care about bots being a thing with the increase in frequency with special mm tanks being more popular so why not bring -1 or +1 for certain tanks at tier 10 and 9, because most of the time tier 8 game are fine when certain tanks ain't in the mm
