Yes, we have noticed the increase in match making times but it is a known issue that would arise from the new PSR system. One thing that drives this is that we increased the amount of time that the match maker sits there looking for an exact Tier match. This means the 'release valves' from the previous systems aren't kicking in as soon as they used to.
Previously, the release on skill matching would kick in at 45 seconds. With PSR this was increased to 60 seconds. This is working well in terms of match quality for the solo queue but is causing rather long wait times for the group queue.
That being said, we have reduced the amount of time the match maker looks for exact matches in the group queue to 30 seconds. It's not going to make the wait times drastically shorter but it should help noticeably overall.
This was applied yesterday afternoon. Hopefully across the weekend we can get more data as to how this affected the group queue wait times.
Having to wait 20 minutes to find a game with a 4 man in unacceptable.
