What are Riots Ideas of an "S"
So recently, I played a game.
It was Lulu mid, against a Lissandra. I had a relatively easy time in lane, got a few ganks, a few kills. From around 8:00 to 30:00, I was basically the monster on the Summoners Rift, running around, getting solo kills, taking objectives, and saving teammates. What I mean when I say this is that my final score was not a result of running around the map and ksing, and I got more than my fair share of assists as well. We won the last two teamfights off my ultimate and my polymorph, and I finished the game with the score 16/2/23. I had second highest damage on our team, placed the most wards, and stayed high up on the charts in terms of damage. I also had third highest gold in the game.
But I only got an A+.
In fact, both the Sejuani and the Alistar on our teams got S.
Now, this isn't me raging at Riot for not geting an S, but instead an investigation into a question I have had for a long time. What are the standards/requirements for an S? I always assumed it was lot's of kills/assists, very few deaths, and tons of damage. But despite meeting those requirements, I still didn't see that glorious S on the Post-Game screen. So what did I do wrong?
