Ranked Matchmaking Update:

• We have adjusted the matchmaking schedule to not be split across many different hours throughout the day, primarily to help address queue times. There will now be a wider continuous, but more concentrated, set of hours that it is enabled in. The schedule is now more simplified as well, as there is no more user selection component.

Update 2 from about half an hour ago:

• Ranked now has weekend specific hours (starts 5 hours earlier)
• Fixed some regions (South America, Oceania, Asia) that were off by 1-2 hours from their intended times
