Champion Grades

Dear Riot,

I have come to you because I, and I'm sure many others, want to know what EXACTLY we are being graded on when receiving our champion scores after games. Example: I went 2/0/32 Soraka Support, a perfect game and was very happy about my performance and effort throughout! It was very disheartening though to discover after game that I received an S- and failed to acquire my M7 Token. Don't get me wrong... I am sure there are better players then me but knowing exactly what it takes to receive an S/S+ (or any grade for that matter) would go a LONG WAY into lessening that feeling of being screwed over after playing a flawless match. I was really posative and encouraging to my team, I had great postitioning, and overall really stepped up my effort to being that "Model League Player" you so encourage us to be. But when that isnt rewarded it really makes us feel like we put in all that effort for nothin so why do it again if im not gonna get the outcome I really desired. Dont get me wrong, I had a really fun game! But i didnt play Soraka for the rest of that day cuz it was frustrating feeling like I was cheated from what I worked to earn. That all said, please break it down for us! Give us a chart of what exactly we are being graded on and what it takes to get what grades with which champs.
