S Rank?

Yea as the above guy said, those comments were really dumb and it is in fact KDA, CS, objectives, wards placed.

In addition, it's measured by the averages that players normally achieve when playing your champion. (so a high KDA on a champ like Fizz would not mean as much as on a champ that doesn't normally get a lot of kills)

Wow these comments are stupid. It's KDA, creep score, and objectives. You can go 30/0 and still not get an S if you don't CS

I'm starting to wonder myself.....the only person who got an S in that game was the Vlad.

My first S rank game since the chest system was introduced was a game I actually lost as kindred (7/9/3) so I have no idea how this works anymore.

KDA

But how am I supposed to get an S if I'm a support and I don't cs ... I went 2/0/13 with Naut and only got A+ xD
