Matchmaking
- Fixed a bug where "Loss Prevented" was showing up as Defeat in the post-game lobby and in the Match History.
Context: As a new player, it's no fun going through unbalanced games while the system tries to figure out your appropriate skill level. We've done some work here to speed up our ability to identify new players while quickly improving their matchmaking experience.
- New players will now have their appropriate skill level identified faster in the matchmaking system.
Context: Explanation here: if you've been waiting in the queue for a while, the matchmaker will become less picky about making a perfectly balanced match. That said, there was a rare bug where players who were in the queue for long periods of time would become matchmaking vacuums, where they would instantly suck in all of the more "picky" players who had just queued in the nearby matchmaking vicinity. To the vacuumed player, if a match gets found quickly, that means in our system that the match is guaranteed to be high quality. Occasionally, however, this wasn't the case (due to wider ranges in matchmaking confidence), and can lead to a bad experience – we've since fixed that bug.
- Fixed a rare bug where the matchmaker would create imbalanced matches when a player had been in the queue for a very long time.
