A: Yes, because it compares the opponent's MMR to the player's displayed rating. This is common when both players haven't played many games, meaning their MMR is higher than their displayed rating. Bonus pool affects displayed rating, so someone who has an unused bonus pool (a bunch of accumulated points) is less favored than the same person with the bonus pool used (as they are essentially free points). Does this mean that with say, 150 points saved you are better off losing 10 then winning 10 than winning 10 then losing the same 10 (as the use of the bonus pool will make those losses much larger) ? We also have this question that directly answers that: Q: Is the bonus pool considered in any calculations? How can that be accurate if it constantly inflates ratings? A: Because everyone has access to the same total amount of bonus pool, it's unlikely that it is included in any matchmaking calculations. However, this can be interpreted in two ways. Either the max bonus pool is subtracted internally from everyone's rating (similar to global rating decay), or only the consumed bonus pool (the inflated portion of your rating) is subtracted. Say you have two players in the same league whose MMRs/points have stabilized. Player A has 500 and Player B has 300. Player A has consumed 400 bonus pool and Player B has consumed 150 bonus pool. If the max is subtracted from everyone, then A would be higher up because B's unspent points are working against him. If not, then that means that their "true ratings" are 100 for A and 150 for B, so even though A has a higher displayed rating, B would be higher up. We don't know which is the case, but we could speculate that the "true rating" design would be more accurate because it's a fairer design. | ||

I was under the impression that your overall points where divided in half every time you go up a division. I had a friend that was in platinum with 1200 points and when I checked him a couple days later he was diamond with 700. It made me assume this though he could have just lost a huge number of games in a couple days  You do lose some points, but it varies per player and probably more specifically by games played. That is, when I got promoted to Diamond in 1v1 I lost 63 points and was 16-9. When Vanick got promoted from Bronze to Silver he lost 12 points and was 5-5. There's some formula at work, but it's not obvious what it is and certainly not as simple as "we just halve your current points". | ||

It makes sense that they would in fact subtract the bonus pool influence altogether for calculations. As for the purpose of bonus pool it is just to make WoWbies (you know, blizzard's customer base :/) feel like they are improving rather than stagnating. This also means that there is no set "good" point count but only a relative one (what was 600 diamond is now 1000 diamond and will be 1500 diamond in a month most likely). Logically the "real point-bonus pool" should remain somewhat static (and be a good indicator of improvement or not. In fact if someone were to start a new team or get their placement done, tell us the value of the bonus pool, we can divide by the time since release to get a decent approximation of the exact bonus pool input and from there determine the "real point - bonus pool" (where top pros are probably about 1200-1400 and I would be 500 rather than 1100). | ||

I can't find any threads that talk about this subject but maybe I'm not using the right search terms. Does anyone know anything about this factor in advancing leauges or is the calculations too obscure to figure out? | ||

Blizz's secret ranking (MMR) is the only thing guiding the system. Point in case, I'm a 1200 Diamond 2v2 player now playing the 1v1 ladder. I was placed in Platinum but play almost exclusively Diamond 1v1s in the 1100 range (probably 15 of my 23 games have been this) all of whom are "favored". When I win I get big number boosts to "fast track" me to that level where Blizz thinks I should be. I suppose, once the system gets more data, it will level me out and I'll start playing more "even" matches. It's a good system IMO. | ||

What's the point of a system that is supposed to give you an idea of your skill level, if it is highly inflationary? I don't think you're using Elo in the proper context here, which is why I dissuade anyone from using that word. There's displayed rating and there's MMR. If you mean that the displayed ratings will never cap out, then yeah, that's probably the intent. Keep playing to hold your position. Your relative position though won't change due to inactivity. | ||

I'm currently rank 1 in my Platinum division, and I've constantly been playing Diamond players that are around rank 40-20 (I haven't checked ELOs). My matches always say "even match" on the load screens. I've also been on a 9-win streak against these same kinds of players, going 15-3 for all of my games today, yet just like this last month I'm still stuck in the top of Platinum. Will I ever be moved up? I keep playing Diamond players and have been since release, yet I've never been bumped from Platinum . I've never gone on a losing streak more than 4 losses in a row, although you say that that shouldn't matter. | ||

If that's you, I see you had a 9 game losing streak just six days ago, that must have caused your mmr to plummet. Today you had an 8 game winning streak but most of the games were against people around your skill level (11 points means practically even I believe) which means your mmr is still not high enough for diamond yet. Even the one game in that winning streak (3rd game in the series) that you got 14 points from, it was against a platinum 900. I think you will know you're close to getting promoted when you start getting 13-15 points per win more often, as that would mean you're winning against people that the system thinks are better than you. | ||

I'm going to assume that the "Top 200" Blizzard posts is based on the hidden rating. I have a friend that hovers around 1500 points, playing completely actively, and yet still doesn't get into the top 200. (yes, he's diamond) Does this mean he's lost a lot of matches that bring his hidden mmr way down, but win ones that don't really bring it up? If you give us your friend's character name maybe we could help you. | ||

A: An exclamation point means that the player has been placed in that division but not played any games last week. This is wrong, I haven't played any 1v1 games for well over 2 weeks and mine still has a green arrow. | ||
