This 1.0 spread in the matchmaking for heavy tanks does not work. Most of the balance problems in this game is caused by it. A downtiered heavy tank is a license to club the entire enemy team single-handedly … get uptiered and your cannon is literally the most useless on the entire team.
I’ve seen an IS-1 fully downtiered get 22 kills in one match without dying. The only way to fix this is to reduce the BR spread for heavy tanks and force it to be selected as the first spawn for the player so they can’t just select a medium tank instead.
Quantitative matchmaking would also be a welcome change because I’ve seen teams with 15 heavy tanks of GER + SOV and it’s literally impossible to defeat them.
