- CS number 1 priority
- Don't fucking Die so important
- Get Vision: Having a 20/0/12 KDA and amassing 300 farm at 30 minutes will only get A+ if your vision score sucks
Getting Kills seems to be waited against your deaths so if you don't die you there is no impetus to go Rambo and annihilate the enemy team.
I actually don't like the ranking system as there are times in League where giving up your life is the most advantageous thing to do. Like baiting the enemy team close to the bush your 750 AP Malphite is lurking in with his finger poised above the R key. Playing safer (and giving up leads) seems to be the surefire way to get an S. When Zed dives the backline or your jungle gets caught in the river and you got a stacked minion wave you have to dip on him. Playing to win and playing for S rank are two different things in League. They only sometimes correlate.
Also the S is stacked against statistics of other players who play the champ. So broader appeal champs will have lower requirements to get an S while getting an S with Gangplank took me as long as it took me to get Mastery 5 with him
