I've uninstalled StarCraft today. Due to TL's rules I can't be specific, but I wish you good luck in this game where Blizzard doesn't give a shit. It's really a childish fix from Blizzard to inflate masters league to keep people 'happy'. It didn't work for me despite promotion. There are much bigger problems than easier promotions could solve.

I don nou what happening with the system that assign leagues, the other day i saw a terran diamond player with 50 apm, i could understand a protoss player with 50 apm that got diamond with cheeses and allins, that situation existed and will exist, but when i saw a terran diamond with 50 apm, i realized that is something wrong with the new system, and the massive promotion to master, basically now leagues doesnt mean anything.

Are unranked matches included to those 25 matches? Let`s say i`ll play 15 unranked matches and then 10 ranked. Does the calibration grabs then too? Afaik unranked works with the same mmr as ranked does!?

No. Ranked and unranked MMRs are separated. But it is likely that similar calibration period happens for unranked too (hidden placement matches and possible calibration period after that).

That has been the case since they removed demotion (?june 2013?). Statistically, the % of players in masters would get to 100% if everyone played an infinite amount of games.

I don't think the threshold removal will have such an impact. To my understanding, they only promoted when MMR got to ("lower_bound" + "threshold"), where "threshold" is the estimated standard variability of a player's MMR for a fixed skill.

Removing the threshold only means that players at ("lower_bound" - "threshold") will get promoted at the highest of their standard variability. This is something that can easily enough be managed by redefining the bounds themselves.


They're promoting people when their peak MMR hits X for one game, instead of the previous system where they promoted them after their peak MMR hit X+Y+Z (no more variability taken into account and no safety margin). I think it'll have a pretty big impact - with no demotions anyway, it's only a question of how fast masters+diamond inflates

Even before the changes the uncertainty did not affect the accounts noticeably after calibration period was over based on MMR tool data. The MMR changes were quite predictable after the stabilization had happened

And the safety margin that was there was likely quite small as there usually was no zigzagging near the threshold and most accounts were promoted with about the same MMR levels. Do remember that you can get pretty much similar effect that you got from a small safety margin just by adjusting the league offsets / thresholds. If the initial offsets / thresholds are not optimal, Blizzard can adjust them after the dust has settled (when majority of the accounts have stabilized and reached their 'typical levels').

It is shame that too many are now only looking at the league percentages on nios. The percentages are not that relevant at this point. The thresholds can be adjusted if the initial guesses (estimates what static offsets / thresholds would be ok) were not on spot and the league distribution ends up being off. The more important effect is that the MMRs should become skill ratings once again when enough accounts have went through calibration. And if the MMRs end up corresponding the skill levels better, the matchmaking improves.

Me too. But even back then people complained a lot about the ladder. But at least the ranking system was clear. Yet there was no auto matchmaking. It was basically managed directly by the players in the way games were created

Same here. After being re-ranked (5 games placement, got cheesed by 3 different 50 APM tosses. God how I hate this game sometimes. Inferior players shouldn't win because of single units abilities) to silver I had 100% winrate and after 15-20 games went to gold, 1 game later plat, 1 game later to dia. Where I still win, even offrace
Looking forward to the LotV invite

I'm loving the changes, quite a few of which seem to be a return to game-launch league outcomes and common-sense adjustments since players cannot be demoted in a season. Good riddance MMR decay.
