Even though I win when I get my role I perform statistically poorly.
According to champion.gg I perform poorly on pretty much every champ I have 2+ games on. http://www.lolskill.net/summoner/NA/KilljoyX/champions
I have no idea what I'm doing wrong, or for that matter right beyond objective control, but it annoys me that I perform poorly relative to other people playing the same champ.
