PSA Regarding ranked placement and seedings for all who are confused
TLDR: The ranked system is actually a combination of a pair of systems whose interactions cause some odd things to happen at the beginnings of seasons. They may be flawed, but they can also be exploited if understood. Take the time to read if you want real answers to why you were placed where you were, and keep in mind that none of the information here is exactly how things work, its just very close. For a shorter version of this thread look here: http://boards.na.leagueoflegends.com/en/c/GD/p1ETKBzH-i-got-placed-in-x-division-after-placements-why-guide-inside
I've been responding to these threads all day, I figure its better to just do this and create a thread to explain the issue on a lot of players mind's.
Many players, at the moment, are concerned about how placement matches are working because they are placing lower than they finished the previous season. Let me begin by explaining the reset algorithm and how it works:
(Previous season's ending MMR + 1200)/2 = Reset MMR
This algorithm is how your new MMR for the new season is determined. This MMR is calculated prior to you playing any of your placement matches. If, for example you had an MMR of 1000 before today in ranked play your MMR after the reset would be 1100, (1000+1200)/2=1100. This MMR range roughly equates to high bronze/low silver.
It is probably also important that I explain the way the League System and MMR system works. In the past, prior to season 3, we had what was called the ELO system for determining a players ranking. After that, the terminology of ELO was replaced with MMR (match maker rating) and was overlaid by the League System which uses League Points to move you up and down what are called Divisions and Tiers. The amount of LP you gain or lose from a match is determined by your MMR relative to that of the opposing team. If the opposing team has a higher collective MMR than your team you will gain slightly more LP (and also gain slightly more MMR) and lose less. Naturally the opposite is true if your team has a higher collective MMR than the opposing team. Your MMR is not displayed, and is a hidden element working behind the scenes of the overlaying League System. In essence, we still operate based on the old ELO system, just with a different way of displaying the information its responsible for processing. Naturally this can cause some confusion, particularly in the beginning stages of each new season.
Many players are confused as to why they are placing lower than they finished at the end of preseason. The truth is this is normal. You have always, ever since season 2 (except for players who finished season 1 in bronze), started the new season at a lower ranking than you previously held. You always will begin a new season at a lower ranking than you previously held, this is normal. In fact, it used to be worse. Under a hard reset EVERYONE'S rank was reset to exactly 1200 MMR. Bronze through challenger. This caused a lot of chaos on the ladders in the early portions of seasons and was widely considered to be a bad thing, thus we got soft resets that work according the aforementioned algorithm.
It is probably now best if I explain what the tiers break down to MMR wise. Keep in mind that since Riot won't explicitly release the information regarding the exact MMR levels and breakdowns that this information is approximate, but it is indeed very, very close to the actual values. The expected MMR range of tiers breaks down as follows:
Bronze: 0-1099 MMR Silver: 1100-1399 MMR Gold: 1400-1699 MMR Platinum: 1700-1999 MMR Diamond: 2000-2500 MMR Master: 2500 MMR + Challenger: 3000 MMR +
Thus we can see that the starting MMR point for an account that has never played a ranked game, 1200 MMR, roughly equates to Silver 4. The 50% point on the ladder. Roughly half the players on the ladder will be above that MMR rating, half will be below it.
It is now important to keep in mind that these are the EXPECTED MMR value ranges of these tiers and that the League System overlays the actual ranking MMR system as it is the League System that is publicly displayed while MMR is kept hidden. This is vital to remember because it means that players can achieve a displayed ranking that does not appropriately correlate with MMR system's expected values. For example, a player could lose his first 100 ranked matches and achieve an MMR of 0 and a ranking displayed of bronze 5. He might then win his next subsequent 50 matches and be promoted to silver 5. However, his MMR will still be roughly half of what was lost, or, approximately 5 or 6 hundred. This happens because of the way the League System functions using LP to change the displayed ranking while still using MMR to determine how much LP is gained or lost.
Many players are concerned because they feel the ranking they have been placed in does not feel like the ranking they deserve. This is true! Because of the way all these systems work together you are placed lower than you previously finished because the systems expect you to be able to easily climb back to your previous ranking inside of 50 total ranked matches. So do not freak out if you have placed fairly low. It could mean a few things when this happens. Perhaps your last previously displayed ranking was higher than your MMR would dictate you rated and you achieved a displayed ranking higher than the system would expect you to have based on your MMR. Perhaps you lost more placements than the systems expected you to lose. No reason to fret. Your MMR is still where it should be and because the system has placed you in the appropriate tier and division for that MMR your ability to climb will likely be easier than it was previously. If, for example you finished the season with a displayed ranking of Gold 5 but only had an MMR of 1200 you would only have been seeing LP gains of 12 or 13 per win. This makes climbing very tough! You lose more for a loss than you gain for 2, or even 3 wins! OUCH! However, since you have now done placements for this season and been appropriately ranked according to the MMR breakdown you should be seeing LP gains of 20-24 for a win. That's much easier to climb with! This is why the system expects you to be able to quickly achieve the same ranking you previously held within 50 total ranked matches.
It is no different for higher level players. I have an account that I made for last season with the sole intention of one tricking Evelynn to diamond. I sadly fell a bit short of my goal and ended the season with about 1950 MMR in platinum 1. No biggie, I was new to the champ and the role pretty much and it was a fun challenge to give myself on ev3carriesu for the season last year so achieving the same ranking as my best accounts in high diamond wasn't exactly a given. I will begin this season with that account, when I take the time to do placements on it, at approximately 1575 MMR, or in the mid gold range. That's a significant drop! But no worries, I cruised through that MMR range and, having had a whole year to improve my Evelynn play I will likely cruise through it even easier this time around. If I should get a bit lucky and win all 10 of my placements I will have gained roughly 250 MMR and bam, presto, that account will be placed in low platinum, most likely platinum 4. The system actually expects me to win 9 or 10 of my placements because I will be playing far below my skill level in a much lower MMR range, and since pairings use MMR to match you with opponents and teammates as opposed to the League System's displayed ranking its probable I do in fact win 8 of my placements minimum (I will be waiting for a few weeks to do this as doing it now I would be playing placements against other high plat and low diamond players which will make winning tougher, so I'll wait for the majority of players to place before I do mine and beat up on actual gold level players, cruel I know, but I do this to make the subsequent climb faster and easier. Apologies ahead of time to those I beat up on). Should I win about 25 of my next 40 matches I will have regained the platinum 1 ranking it had and probably be a handful of LP short of diamond promos. This is a personal example I give to you folks to show what the system expects and why because of the way it is designed and the way the League System interacts with the MMR system.
To all of you folks who are upset about placing lower, do not worry! It means nothing, only that the system expects you will easily achieve the correct ranking in the next 50ish games and has placed you lower to err on the side of caution. Most players improve from year to year and season to season and will quickly outpace their previous rankings. If you are playing on an account that has never before played a single ranked match the placement system will work differently and, should any of you have questions regarding how that works (although the interactions with Dynamic Queue may make some of the past workings obsolete or slightly different) feel free to ask me and I will explain in detail how placing a fresh account has worked in the past as well.
I hope this has cleared up any confusion you folks may be experiencing and I wish you all the best of luck on the RIft! May the force be with you and the odds ever in your favor!
Edit 1: Added a TLDR and this link to a post with the advice of another high level player. http://boards.na.leagueoflegends.com/en/c/gameplay-balance/jyUuJfBp-season-6-advice-for-climbing-in-rank
Edit 2: Added Ebay Accounts shorter version explanation as a link in the TLDR for those looking for a briefer explanation.
Edit 3: Since this has also become a bit of an advice thread I'm including another link to some advice from Bella Blue about the best times to play ranked here: http://boards.na.leagueoflegends.com/en/c/GD/WHEQAX5x-bellas-guide-to-playing-ranked-at-the-proper-times?page=1
Edit 4: As promised I used a known account with known MMR qualities to perform the same experiment as last season. The account SecondChanceHero, which finished this preseason with about 1650ish MMR ranked in gold 3 has completed its placements 9-1 and been placed in gold 4, confirming the system works exactly as I have described in this post and this is the second season in a row this account has demonstrated how the system functions and performed this experiment. I cannot check the MMR for this account yet because op.gg and lolking have not yet updated, but I will update that information when it becomes available.
