This is not a debate. You are objectively wrong. Nothing else you wrote is even worth reading if youre going to ignore the games director in favor of a random statistic from a nobody site lol
Why dont you actually compare the stats between plats and diamonds? While were on the stat argument Moira has one of lowest winrates of any support even in Bronze. I guess that isnt convenient for you though.
And you keep ignoring the game director and what he says the average is because its inconvenient for you. Its not the majority. The combination of Bronze and Silver literally doesnt even overtake the amount the players in Gold alone. Bronze + Silver are neither the majority or the average.
