i once heard that will be a pro-ladder above the platinum and the top 8 of every Division will be promoted to that ladder. But your explanation makes more sense. Good Job.

more skilled players won't be placed in earlier divisions unless there are more skilled players playing at the very start of division formation (this would be explained by players who play more frequently being placed earlier.. which is sort of speculative). If you have 100 people, you can assume a set number (let's say 15) will be placed in platinum. This happens regardless of the groups overall skill level. It has nothing to do with a win ratio in placement games skewing placement towards platinum. Since players can be demoted from leagues as well as promoted, there will be no collective movement of initially placed gold players filling the ranks of later platinum divisions without some equal demoting of platinums. The effect will be relatively even skill levels across platinum divisions barring the possibility of more frequent, high skill level players being placed earlier.
It is not enough to conquer; one must learn to seduce.

so to get this straight (because i was discussing it in another thread): the main supposition here is that it's got nothing to do with divisions who you're matched against, meaning you don't play people from your own division more often than people from other divisions?

my assumption went along with what the following person said:

On April 03 2010 18:17 Dyno. wrote:
In addition to what people have said about being evenly matched, there have been cases of people being "promoted" from one platinum division to another. It was a bug that blizzard has since fixed. However, when this happened, the player's rating would be significantly different in their new division compared to their original one.

It happened to KHB twice on different accounts (whatever happened to him anyway?).

Edit: And to address what someone said earlier about the matchmaking system not favoring players in your own division, this is generally believed to not be true. It seems fairly obvious that the matchmaking system will attempt to match you with a closely-rated player in your own division before searching the rest of the league, and then expanding to other leagues. If the #1 and #2 players in a division are queueing up at the same time, they will almost always get matched up together. This is why we saw such things as IdrA and CauthonLuck playing so many games against eachother prior to the reset (they were both top3 in div 4).


if that was true, how can you compare ratings across divisions when the generated ELO depends on the players you are matched against (and players from your own division WOULD be favored)?

sad that we have no contact to the person(s) who stand behind this matchmaking system and could easily answer the question if it does or doesn't play a role in which division you are and what opponents you get accordingly.

Given how much testing they have done with WoW, it seems pretty logical to assume they would use a very similar system for bnet 2.0. Good read, solid reasoning.


if this is anything like wow's arena rating system i will be severely disappointed.

being a 2300 3v3 wow arena'er myself, i'd be really mad if they made it the same.

the arena match making system im wow is so messed up right now... jesus. i really hope they do more testing

this is my first post here and since i come to this website for useful information concerning strat and i saw that no one wrote any numbers concerning promotions, i thought i should add something ...

i was copper division 55 and after being first for about a day once i hit 1300 points (2nd guy was 1233) with my 69th game i was promote to bronze. i was added to bronze div 80 and straight away i was rank 9 with 1039 points.

hope this helps on finding how the system works

edit: oh and my bonus pool changed from 0 to 52.
last edit .... maybe: when i joined i was rank 9 with only 1039 simply cos most people in the group had 1000 points cos they just joined on that day with 5 games. also on closer inspection there was 47 people in the division so a new one i gues. and rank one in that group had 1242.

About higher skilled players being in lower division numbers statistically. I'd expect that to be true only for the first season. I'd seems (to me) very likely that divisions will be redistributed periodically (probably at the start of a season), with players being evenly distributed based on their skill (i.e. MMR most likely).

If this is not the case, I feel sorry for that nice guy that got stuck in division 666 with all those BM players. Or less exaggerated, it should be refreshing for everybody to have a new set division mates once in a while.

got placed in bronze, after about 10 games i started playing only platinum and gold people, went 20-12 and got moved to silver, played sooo many games and went 65-49 against mostly platinum people and moved to gold, went 100-70ish and got moved to platinum...just kind of weird that i played platinum people regularly almost right from the start but it took almost 200 games to get there. my win record isnt good but still..

I am a pretty bad casual player at SC2 (30 APM max, often supply blocked, often can't build things fast enough to makro properly on 2 bases), but was very lucky at my placement matches - I got paired against 4 very weak players first and stomped them. 5th opponent was good (280 APM) and I had no chance.

So I was put in Gold with my 4-1 score, set 1000 (ELO?) points initially.
Thought that I would get stomped here like opponent 5 did - at least until I am releveled to Silber or Bronce. But surprisingly, I am still matched against opponents, that I can sometimes beat (now at 970 something with a 8-6 score).

So whats the point of my story? 5 placement matches are probably not enough. But even if you are running bad in your league, the system does a good job in finding suitable opponents for you. Just wondering when the system will find out how bad I am and relevel me - so my goal is to try to stay in Gold as long as possible.

Finally sorry to all the decent players that get paired against me and might wonder: "What the hell is this guy doing here in Gold?"

well, if you keep hovering around 1000 pts in Gold, you definitely belong to how the current gold league is defined

but 14 games isn't much, keep playing and see how it goes, if you drop below 900 you will probably be demoted

there's a huge difference between high/low plat players, being able to win against low ranked plat players is usually not any more an achievement (or a representation of skills) than winning against top gold players (say, with 1250-1300 rating)

plus, if you have a winning rate not that far above 50% against those players, maybe it was a good thing the system did wait for you to play more games before moving you from silver to gold and from gold to plat, don't you think?

Thanks for this post -

I still don't understand why I got demoted after I win every game where the other team is favored (2v2 random.) Stayed around 1000 while going 1:1 (or a little over) and still got demoted.

Ah well, thanks for this post and hopefully blizzard will clear things up a little more. I'm assuming every time the other person is favored they are A) In a higher league or B) same league but more points. According to the OP, I should have been promoted then *sigh*


edit: I got demoted on my 20th game, just if anyone cares about that note. Excuse me while I faceroll back up to gold I guess -_-

Great post. I agree 100% with what was said in the OP.

There are plenty of times my platinum ranked friend would crush someone who was slightly favored against him only to find out the other guy was in gold league or lower . I tend to believe the other guy was favored because of one of the following 3 reasons:

1) The other guy had only played only a few games (which he could have won) and thus his MMR shot up way higher then it should have been.

2) He went on a long winning streak, perhaps against some high MMR opponents who were having off days, and his MMR shot up higher then it should of.

3) There are so few people playing beta that everyone's MMR is so highly volatile that there are likely to be huge fluctuations in a single person's MMR. This is can be readily seen because of how quickly the matchmaking reverts to "Expanding Search" thus searching for players largely out of your MMR range.

I also had a thought about the "review checkpoints". I think that the number of games goes up exponentially so as to get you in your proper league sooner and then leave you there for a while so that you can climb that individual ladder. For example: Review checkpoints would happen at intervals like 25 games, 75 games, 150 games, 300 games etc. so you can get that feeling like you have something to strive for as was the intention of the league system.

Long time reader, first time poster.

My question is this (I'd be happy to hear thoughts on this from anyone): If you go 5-0 in your placement games, does that guarantee that you'll wind up in Platinum? Has anyone ever experienced going undefeated in their placement games and still not been placed in Platinum? I'm just curious because its quite possible to play five weak opponents by chance in your placement games and then get placed somewhere you don't belong. Likewise, you could easily go 3-0, then lose to two high-level plats that are also playing their placement games (after a ladder reset), and wind up in silver where you don't belong.

As several people have mentioned, it could take quite a large number of games (100+?) to move from silver to platinum even with a good win ratio vs. other platinum players.

Very informative!

I have a question and wasn't sure where to ask it and couldn't find any info on it...

Was there a ladder reset very recently? I had to play the placement matches again.

Awesome read. Great analysis. Not 100% on everything as other people and you noted. But I would like blizzard to release all there information on how they rank everyone, divisions etc. If higher divisions actually do mean better players or what exactly. Just would like a 100% answer from blizzard. Would help other people in organizing tournaments really. Cause being number 20 in division one might be better then someone top 5 in like division 50. That's not a guarantee either but it would be nice like I said. And they also need to add a battle.net feature to look across multiple divisions and others ranks etc. It will probably be like that on release but I want it now! haha
Has anyone really been far even as decided to use even go want to do look more like?
