These posts will often contain talk about future work we're doing, or planning to do, that isn't yet guaranteed to ship. The work or goals could change depending on what we discover, and projects mentioned may get delayed or even stopped. That said, I believe it’s important to share as much as we can even if plans may change.
We've made some pretty big changes to the LP system during preseason, some of which are easy to see (no more division promos) and some of which are more under the hood (improvements to our matchmaking algorithm). There have been some hiccups during the rollout of these systems, but that's why we do them during the preseason where they have a smaller impact. The end result is that we saw players' ranks being inflated, which resulted in lower LP gains in the short term. We made the necessary tuning and fixes so that everything will be correct with the seasonal reset in January.
With all of the changes for next season, we do expect LP gains and losses to be slightly smaller on average. We're planning to do a smaller ranked reset at the start of the season so you stay closer to the rank you've achieved this year, and removing divisional promotion series makes people climb faster, and benefit more from a win streak. The combination of these two changes would cause significant rank inflation, so in order for the ranking system to stay accurate, we needed to tone back the amount of LP gained per win.
