Current rating system can't accurately place lowest performing players

[Zojha]

That isn't true.

It is. Let's say two exactly equally skilled people people queue at different times, one at off hours where only hardcore PvP players (still) play and the other during peak time where there are also several newbies and moderate players around to be matched with. The latter wins more games than the prior, despite being equally skilled, simply because the matchmaker could also offer them enemies not way out of their league.

So both people are equally skilled, yet both have different rating. Accuracy much? This is actually precisely the fact why wintrading and other such practices work - if you only got matched with the trading group once in a blue moon, it wouldn't have a big influence on your rating and the rating would still be largely valid. Since you get matched with them all the time, the influence of that one group is huge, which makes the practice work- and profitable and the rating very inaccurate. And the same goes for legitimate players that are just better/worse.

Rating can never be accurate without a vast pool of players. That's just a statistical fact, just as you cannot accurately determine a ranking without a large amount of games. A person having a 100% winrate over 2 games isn't necessarily more skilled than one with a 75% winrate over 200. And a person having 0% winrate against the top 10 isn't necessarily worse than a one having a 30% winrate against the bottom 10. With a large playerbase, that's a non-issue, you just don't match people with people way outside their league up or downward. With the playerbase as small as it is, to the point you frequently recognize your enemies by name, that is a big issue that distorts all ratings in the system.

It is.

Your explanation can still apply to large populations of people as well. Queing on during primetime or downtime still applies to large populations of players. I mean people have been wintrading in WoW and still do, player population doesn't change that.

Anyway, you still have failed to address how people not losing rating for when they lose isn't causing a problem. You probably haven't because you can't really say it's wrong.

You probably haven't because you can't really say it's wrong.

Oh, I don't disagree on principle - I just find it a moot point when the rating system has no solid base to stand on in the first place. And if people can still viably wintrade in WoW, it just means that the population at the time of the wintraders queuing is small - so small that the trading teams are matched against each other often enough to make a difference. It makes a world of difference if the matchmaker has 1000 teams to pick from or 2, namely that you'll not be able to play against the same team very often in the prior case, which vastly improves accuracy of the rating.

That's just the population/time bias. We also have our lovely tier biases, because the tier affects how much you gain lose, whereas the matchup scarcely does. Stomping newbies first round grants/loses as much rating as a hard-earned clutch victory in the last second caused by even teams. Being in a lower tier however automatically loses you less points per loss than being in higher tiers. A perfect 50% winrate at bronze would allow someone to gain rating faster than a 50% winrate at silver or gold respectively. (And truly, a 50% winrate shouldn't even allow someone to climb in the first place).

Do I have to mention the bias based on roles and jobs? Not all roles and jobs are equally influential, which again, screws with rating accuracy.

With all these issues, yours just being one in a pile, I see no point in having a rating system in the first place. It gives people the false illusion that it's an accurate representation of skill when it fact, it suffers from loads of issues that make it more of a broad hint.

Don't know why you don't think rating can't be relateable to skill. The top 10 of both Aether and Primal have familiar faces in them. I wonder why? Is it just luck? You sound like that one guy who said your rank is all luck, delusional.

But anyway I'm not getting into issues of player population or w.e. I'm am talking about a issue that everyone has been complaining about and I give a explanation why and how to fix that one problem. You going on about scrapping the whole mode is extreme and makes no sense.

[Zojha]

Don't know why you don't think rating can't be relateable to skill.

I'm inclined to wager because you didn't read my post thoroughly, because I explicitly called it a broad hint, which indicates a relation.
If someone keeps a low rating, he's probably bad - probably because the rating is distorted through numerous factors and there is reason to doubt that the active PvP population is a statistically representative sample for the whole - chances are, good players are more likely to play regularly and there is a selection bias.
If someone rises to a high rating, he's probably good - probably because wintrading and boosting exist and you know it. It happened last season, but surely the guys in question just had a sudden skill explosion/implosion.

However, with the rating distortion factors, you just plain cannot say two people of the same rating are equally skilled - which means it is not accurate - A DRK with the same rating as a WAR is most likely higher skilled than the WAR, rather than equally. It's not accurate in bronze, it's not accurate in silver and it's not accurate anywhere else, because it cannot be accurate under the given circumstances. You could scrap it entirely and have completely arbitrary tier promotion/demotion series instead, better players are still more likely to win those on average (thus having a higher chance of getting/keeping the higher tier) while worse players would stay lower and accuracy wouldn't considerably suffer in the long run. Which is why I think the inaccuracy at bronze you point out is a non-issue and a rating system as such is pointless, seeing as the point of a rating system is to provide an accurate skill metric, rather than a shotgun approach.

And since there is precedence of you making assumptions, let me spell it out: This neither means that the rating system must be scrapped nor that the Feast must be scrapped and I suggest neither. For one, while interconnected, they are not one and the same, for another, there's no point removing pointless systems unless they do harm and the rating system only does harm if you fall for the illusion of accuracy. I do suggest however not to put any more work into it until the population issue is fixed and we can have proper, job specific Elo for our matchmaking rating.

Lastly, I would refrain from hollow ad hominem - it's not good style. But that's just me.

In party que yes, but the matchmaking we are discussing is about solo que. And if they are getting someone else to play their account in solo que, then there is still skill behind it, really doesn't detract from the fact that it's a better player climbing the ranks.

However, with the rating distortion factors, you just plain cannot say two people of the same rating are equally skilled - which means it is not accurate - A DRK with the same rating as a WAR is most likely higher skilled than the WAR, rather than equally. It's not accurate in bronze, it's not accurate in silver and it's not accurate anywhere else, because it cannot be accurate under the given circumstances.

Now you are grasping at straws but what you are saying is irrelevant. If the person playing dark knight gets to a certain rating then they got to the certain rating that is attainable as a dark knight, they are placed where they should be if they manage to get out of the unranked/bronze hole. Class balance has absolutely nothing to do with matchmaking.

And since there is precedence of you making assumptions, let me spell it out: This neither means that the rating system must be scrapped nor that the Feast must be scrapped and I suggest neither.

Maybe you should read what you say first before making the assumption about what you think you said.

For one, while interconnected, they are not one and the same, for another, there's no point removing pointless systems unless they do harm and the rating system only does harm if you fall for the illusion of accuracy. I do suggest however not to put any more work into it until the population issue is fixed and we can have proper, job specific Elo for our matchmaking rating.

There is accuracy the higher up we go. However like I said there is no wiggle room near the bottom of the food chain that there are people who can be considered what worse than others are considered equal to those who aren't as bad. Also you suggesting that a simple fix shouldn't be exploited to help out the current base versus SE completely overhauling PVP to fix the population problem doesn't make a lot of sense, and you should realize that.

Lastly, I would refrain from hollow ad hominem - it's not good style. But that's just me.

It may not be, but it accurately describes the notion that everyone on top must be wintraders, boostees or cheaters. If you skim off the top and have a new top then are they wintraders and cheaters too? It will never end. Before you say I'm making a assumption.

If someone rises to a high rating, he's probably good - probably because wintrading and boosting exist and you know it. It happened last season, but surely the guys in question just had a sudden skill explosion/implosion.
