[Ranked Updates]
1. Rolling out an improvement to Matchmaking in EUW
Within the next 24 hours, we plan to roll out an improvement to Matchmaking that we need to pilot in a large region.
We are targeting EUW, late afternoon PST (in about 5-6 hours). The update intends to better balance autofills vs autofills & secondaries vs secondaries, etc.
Will let folks know if we get delayed for any reason later today.
We want games to be more fair & competitive and not feel like they were decided because there was a large off-role imbalance.
As with any large Matchmaking change, we need your help to immediately diagnose and triage any issues, I will be putting up a thread to comment on any odd game results as they start to come in. This will impact all ranks, but will have a significantly larger effect in Apex ranks (autofills happen very rarely in regular play)
If it goes well, we will start the process of rolling out to more regions.
2. Resolving Master+ LP Gains
We're actively looking into a mitigation to resolve the bad LP gains in Challenger, nothing to share back yet, but mainly weighing our options.
This change would get everyone back closer to +-20LP in wins/losses, rather than +10/-30LP that a few people are experiencing currently (about 30% of Challengers)
It was the result of a hard to find 3rd order consequence bug, which we've resolved.
3. Reports of <10 LP Gains
This should only be impacting Master+ players
Looked into the reports of <10 LP gains, eg. +9LP gains (which shouldn't be possible) and the player did end up getting +10LP for the game.
After looking at the frame by frame behavior in the client, there is a number that ticks up to improve satisfaction, but currently it ticks a bit too slowly, so a player can transition out of the screen before it has fully rendered the final result. (you can see this in the video I've linked)
We are looking to both resolve this issue and the core issue causing the negative gains in the first place
4. Demotions
Last year we made some changes to how Tier demotions worked (eg. Silver 4 -> Bronze 1).
It is possible to demote to 50LP, 25LP if your MMR is low enough relative to your Rank. We fixed some edge cases that were preventing that from being true and so if you have a surprisingly large LP demotion, this is why
