Okay Riot how do calculate your Ranks on champion masteries? I just went 18/5/10 and got an A- yet my teammate had 10/4/8 and got an S. Do have to at a certain number of kills, yet under a certain number of deaths? Or is there some kind of formula you use because I just don't understand it anymore. I realize it is(or might I don't know really) based on the KDA score but still again how do you even calculate that? I'm just wondering because I hate it when I do really awesome yet get an A when my kills out number my deaths by more than three times those deaths and even my assists were twice that? Could you at least tell us how you calculate your KDA scores? Thanks and have a good day.

it is a function of damage dealt to champions(+),damage taken(+),objective presence(+), deaths(-), K+A(+), and gold earned (+) normalized to game length, the champion you are playing and your role.

your teammate could have contributed more to fights dispite having a lower kda or he cold have gotten more objectives

I once had a game that was like 5/5/20 that was S+ since i did more dmg than the rest of the team combine.

Different roles aim for different amounts of kills and assists and the game calculates that. It is much easier to get as s from supporting and getting like 20 assists than it is to adc. You also need very minimal deaths

It depends more on the champion and role, so if you play a very common champ in a very common role, you are compared against more players/games, and have a smaller chance of being in the top whatever % S class is.

Annie top is (theoretically) easier to get an S on than Annie support, which might be easier than Annie mid, just because you rarely (if ever) see Annie top.

Then there's some formula that looks at just about everything of impact (I've heard it counts wards too) and gives you a score, then the system sees where your score sits on the continuum for that champ/role combo, and spits out a grade.
