Sorry if this is the wrong place, I've never posted here before, but anyways.
Me and a friend played a game. They got an S- on Annie and I got an A- on Morgana.
Here's the stats of the game: http://puu.sh/oXSvc/c9a25cd9a2.png
Where did I go wrong in not earning at least an S- rank? I'm not really sure how league gives out rankings. I've had much lower Kills/Deaths/Assists and scored higher on Morgana. Just trying to get an understanding of it all.
I have sometimes wondered the same thing but you have to consider that the game rates on averages by your champion in your position. It looks like you were middle lane and Annie was support. Middle lane Morgana with only 105 cs is honestly pretty low. CS is an important part of the rating system. An example is a game where I went 17/1/6 on Galio which is great no matter who you play and insane on Galio but I had sub par CS for a 30 minute game and almost no participation in objectives simply for the fact that I was fighting enemy champions all game. I earned an S- for that score even though it would be an S+ in most cases.
