Helpful insight to the Rating System in League of Legends
Ok I have been seeing a lot of these threads start to pop up lately. "I went 20/0 and only an A? WTF RIOT" "Why can I go 99999/0 and get an A while someone who goes 1/0 gets an S?" You know, those threads.
I am going to partially explain what I have figured out, it may not be exactly how it is done, but it should be close enough for now.
Lets first give hypothetical best's for 5 champions. Lets say its Darius Top, Shaco Jungle, Victor Mid, Ashe ADC and Sona Support (nothing to do with the fact I main Sona... ok maybe it does. ) These 5 were not all in the same game but all 5 had the same game length of 40 minutes for continuity (I do not know how time factors in to this. It still evades me.)
Kills/Deaths/Assists: self explanatory
CS Total/Minions/Jungle/Enemy Jungle
Objectives(includes assists): Tower, Inhibitor, Dragon, Rift Herald and Baron (I added these two together.)
Wards (Vision, Yellow and Blue Trinket), Control Ward, Destroyed Wards.
Damage: Self explanatory
Healing: Self explanatory
NOTE: THESE ARE NOT REAL VALUES THESE ARE ALL EXAMPLES. THEY MAY OR MAY NOT CORRESPOND IN ANY WAY TO HOW THE CHAMPION IS PLAYED!!!!

Sona Support:
Kills: 10 / Deaths: 3 / Assists: 38 CS (minions): 12 / CS (Jungle): 2 / CS (Enemy Jungle): 1 / CS (Total): 15 Wards: 45 / Control Wards: 3 / Wards Destroyed: 15 Objectives (Towers): 6 / Objective (Inhibitor): 2 / Objectives (Dragon): 4 / Objectives (RiftHerald/Baron): 2 Damage to champions (Physical + Magical + True): 45K Overall Damage (Physical + Magical + True): 88K Healing: 47K
AGAIN THESE ARE MADE UP VALUES FOR AN EXAMPLE!!!!!!!
Now If you went 28/0/19 on Darius you would expect to get an S right? Wrong, KDA is not the sole determining factor. I estimate with the example top player you would have to have about 255 CS, Place at least 5 wards, be present for at least 9 objectives, Deal over 130K Damage to champions, and have an overall damage of at least 440K to get an S-.
Same goes for all the rest, you need to be performing in the top of the spectrum to get an S- - S+. There may be some exceptions though due to weighting of certain aspects of roles.
Like lets say you are the Support Sona. You go 0/1/28, 12 total CS, 52 wards placed, 4 control wards, 21 wards destroyed, be present for 4 objectives, deal 23K damage to champions, Deal 51K total Damage and Heal over 75K, You will still end up with an S. You got 10 less assists, no kills, did less damage and was not part of a lot of the objectives. But you did place more wards, destroy more wards and heal a hell of a lot more. Those would be what I expect are more weighted as a support.
For an ADC I would expect Minion CS, Kills, Damage to Champions, Total Damage and Tower/Inhibitor Objectives to be weighted more.
There are also cases like this: Jungle 1/0/1 Shaco S+ vs 21/0/12 Shaco A+ You may be wondering why the hell is that possible. 1/0/1 Shaco Total CS: 380 / Jungle CS 120 / Enemy Jungle CS 140 Dragons: 5, Rift Herald/Barons: 3 Towers/Inhibs: 13
21/0/12 Shaco Total CS 220 / Jungle CS 140 / Enemy Jungle CS 40 Dragons 3, Rift Herald/Barons: 1 Towers/Inhibs: 7
Do you see the difference? The 1/0/1 shaco was present for more objectives and went to counter jungle the enemy more often. There for he got an S+ while the shaco with more kills got an A+ for his lack of objective and counter jungle presence.
I hope this helps all of you who seem to think KDA is all that matters.
