PSA: WHAT IT TAKES TO GET S RATINGS

ZED G0D·Mar 17, 2016·34 votes·14,106 views

KDA Is not the center of the universe when it comes to your grade! Here is what is taken into account:

CS (Creep Score)

Objectives killed (Dragon, Baron, Scuttler, Towers, Inhibitors)

Wards

Kill participation (Game score is 30-10) You're 13-0-17 you're doing awesome keep that sht up 100% participation (you don't need 100% to get S but you get the picture)

KDA (Kill,Death,Assist) Yes your KDA does go into account, but like this list, it is only a fraction of what is calculated in the Grading algorithm.

Hope this helps...Happy treasure hunting!

Please don't spread false information, we don't know what it takes to get a high mastery rating.

While I agree that those things are likely a part of it we can only guess that they are. Unless you can provide a Riot source which proves your points.

Well, it's obviously not KDA alone :/

Brand "support" lol

kDrakariMar 22, 20161 votes

I've heard that mastery scores are assigned based on performance relative to other players of the same champion.

Thus if you take a champion that normally doesn't get kills, then get a lot of kills... profit?

Unstoppable MonkMar 17, 201610 votes

Actually supporting, making plays, and generally the cause of the win by taking hits for your team: B

Full swag kill everything dragon / towers / champions / cs despite the moaning of your team: S

Lose: C

Win: A

Lose 4v5 or d/c yourself: D

highest CS of any support. where is my S?

KnoyleMar 17, 20163 votes

I actually got an S playing Taric support. Over 50% kill participation. Placed the most wards. S-

I'd guess the easiest way to get S as support is to do all the things a support is supposed to as efficiently as you can. For me that means warding, baiting enemies, tanking turrets, buff/heal allies, lock down kills, delay enemy pursuits, ~~Being an annoying shit to the enemy team.~~

Thanks for this, I was really confused on what affected my letter grade because some games I went like 11/4/8 and I only got an A+ while 0/4/7 Malzahar support got an S-. Is the list in order of highest priority to least or just the factors used?

No particular priority, Just all the data Ritos system collects to calculate

Alignment of the stars and the price of sweet potatoes in Zimbabwe is also taken into account.

rescuedMar 18, 20161 votes

Well they judge you against others playing that champ in that role. Since malz isn't seen as a viable support, not a lot of people play him there, so your grade makes sense. Your 11/4/8 could have been with someone that is highly played and can snowball very easily, so it's tougher to get an S rank grade on them.

AhhShucksMar 17, 20164 votes

Also, I'm pretty sure upgrading your boots moves you up a whole rating. Like from S- to S, or A+ to S-.

Duke AnaxMar 17, 20164 votes

Also one important thing you should add:

The values are not measured absolutely, but they are compared to other players playing the same champ or the same position.

That means 200 CS on a Tank can be an S rank while 400 CS on a Mage or Marksman may be not.

Stand Alone WolfMar 17, 20161 votes

How is this done exactly? Does this system act as a "National champion/player skill average?" If so, would that mean this "National Average" could increase, thus making it harder, and harder for a player to achieve good ranks? Kind of like how the moon slowly rocks away from Earth 3.78 centimeters a year? That would also mean the more players League gets, the faster the skill average rises. Right?

*That's assuming this National Skill Average thing is how it does indeed work.

Duke AnaxMar 17, 20161 votes

You are not sure how averages work do you? Adding more players would actually reduce skill average. As new players usually have lower than average skill, adding them would lower the average.

Also It's not really tracking "skill" but rather relative performance. As you noted correctly average skill level increases over time, but that is on both sides of the river, so it doesn't affect game per game performance.

And to get an S rank you don't actually need to do good, you just need to do better than most.

Or at least that's how I think it is done. they only said that it does compare the players, but never how exactly.

You are not sure how averages work do you?

No, that's kind of why I asked.

I did however appreciate the needed explanation since I don't know everything, but strive to learn more.

Duke AnaxMar 18, 20161 votes

You are kinda right though that over time it will become harder to get an S rank, but only because people find it easier to do the harder stuff. This effect will balance itself out though. SO that it will always feel the same to get an S rank.

That's why I said it's not measured absolute, otherwise at one point pretty much anyone would get an S regularly.

DrukaiMar 17, 20163 votes

My biggest issue is that it's so incredibly damn inconsistent, and that certain champions are just unfairly punished for how they play.

I just played a game with the highest Kill Participation (and kills.) A higher KDA than our top, a nearly equal KDA ratio to our ADC. Involved in FB and largest Kill Streak. More wards placed than top, more wards destroyed than adc, upgraded boots, helped with 2 of 3 dragons, 8 of 11 towers. Everyone else on my team got S rank, but I got A? http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2127409884/99169?tab=overview CS is relevantish, sure, but it's TOO damn relevant. Because I'd prefer farming the other team over farming their minions I'm now punished. And it absolutely is punishment now that we have keys being locked to S ranks. Which is seriously horsecrap.

FantasySniperMar 17, 20162 votes

The keys aren't locked, it's chests.

Mech0pMar 17, 20162 votes

in the long run cs is going to be the majority of your money... While it may be more fun to 1v1 an enemy and dominate the the gold you get is based off of how many kills they've had since they last died and the cs amount since they last died... So just remember that its much more efficient to farm than fight and will raise your rating by at least 1 grade if its a decent amount... Its also the reason that a lot of lcs teams can stay at the some gold as their enemy even though they have 2-3 more turrets and a couple kills. Never underestimate the power of the cs

Which is one of my main reasons for not liking champion mastery, and now they made it actually matter... At least it only matters maximum four times per month. Still, I predict a lot of rage due to champion mastery from now on.

ImmortalBloodCYMar 17, 20163 votes

So as a support what am i supposed to do to get a S rating?

Go as usual and keep my noobs alive?

KnoyleMar 17, 20163 votes

worked for me.

It Hertz When IPMar 17, 20161 votes

First requirement is victory. Second is to have at least ten assists for every death. Third, play an engage support; ingame stats don't seem to reflect healing or shields, so assists is the only way to reflect your performance. Fourth, ward EVERYTHING. Get a blue trinket and sightstone variant ASAP and spam the shit out of it/them. Fifth, get a few kills. I have NEVER gotten S without at least a few kills, no matter how many wards and assists I have.

EboybiterKDAMar 17, 20163 votes

nope winning isnt a requirement. nice try though

http://na.op.gg/summoner/champions/userName=eboybiterkda

I would know. I lose every game and lead in kills/assists every game. 100 KDA mundo ftw.

kDrakariMar 22, 20161 votes

If you look closely, keeping your team alive isn't a measured stat. In order to get an S rank on support you should make sure to blow all your sightstone charges before recalling and value participating in a kill over not stealing a kill. Generally speaking, ignore the voice in your head saying "You're the support, it's logical to sacrifice yourself to save another team member". Also play well, but those are the easy things to get a boost to your mastery score (assuming OP has good info).

Play off meta picks and non carries. AP Amumu and mid Azir often work for me.

ZED G0DMar 17, 20162 votes

Also something most people will not notice! You Cannot get a chest more than once a day! I believe its weekly? assuming, In you game client if you go to your profile, in the top right corner of your profile you should see 4 chest Icons. It will say "Next chest available in # Days" Self explaining that you cannot farm 4 chests in a single day. Good luck!

ragdollomegaMar 18, 20162 votes

I guarantee that this is not the case. I got 3 out my 4 chests on the first day the patch came in (it was a REALLY lucky series of matches). What I think it is is that your chest count adds up on a weekly basis if you have room to get chests back. Which I see as making sense since that allows you to get chests on a more consistent basis.

Jo0oMar 17, 20162 votes

I'm under the impression that the game "guesses" the role you're playing based on CS and grades accordingly. I've finished games as support going like 3/2/27 with 18 CS and gotten an S. That's a fairly terrible KDA and CS for anything other than support.

But hey, while I'm here: Are you guys actually getting graded? I haven't had a grade successfully load post-game since all this Hextech loot went live.

Stand Alone WolfMar 17, 20162 votes

Riot noticed this issue, and was working on it. You made this post an hour ago, and are still seeing it? They fixed it this morning for me as I finished a match on another account, and saw my grade/rank.

Jo0oMar 18, 20162 votes

At the time of my comment, I had just finished a match that failed to grade. If the problem persists next time I play, I'll seek some tech help. Thanks for the info.

rescuedMar 18, 20162 votes

Yes, the game can tell what lane you are in. So a 3/2/27 mid Lux will probably get like an A rank but a support Lux with that score will get an S rank. You are grading from other players playing that same champ / role.

Jo0oMar 18, 20162 votes

That's interesting, thanks for confirming. So does the system check ADC versus Support based on CS, as I suspected?

rescuedMar 18, 20161 votes

Yup, they can also tell by which items you buy too :)

JalkanMar 18, 20162 votes

Riot has said somewhere that the rating is based on how you compare to to other people's performance with the same champion, same role, and similar elo. So if you play Support Jax, you will be judged against everyone else who played Support Jax.

Imma Solo BaronMar 22, 20161 votes

Welp they need to take surrenders, or game length at consideration, cause i just went 10/0/6 as darius decent creep for the time, took 2 towers, and help with dragon, and got a B+ bc my enemies /ff?? rito pls [zombie-brand-facepalm]

Vistha KaiMar 22, 20161 votes

Yesterday I played Darius once.

KDA: 6/5/0 CS: ~170 Kill contribution: ~12% Wards: like 3 Objectives: 2 towers and one Red Buff

Got S-

It's either Darius players are so bad or champion rank is tied to RNG.

Emerald FangMar 12, 20181 votes

You can get an S- exclusively from cs. I've gone NEGATIVE but still got 9 CS per minute and got an S-. For S and above you'll need a little bit of everything.
