Thats a joke, right?

I always felt getting a S on a jungler is hard. But i just finished a kogmaw jungle game: 13/3/3, most kills, most gold, second highest dmg to champs in game, second highest cs in my team (AS JUNGLER!). we won, i got an A+ what in the name of Braum toplane do i have to do, to get a S? sincerely, a mad euw jungler
