Regions and live events After all matches were rescheduled to be played strictly online due to the
COVID-19 pandemic, the 2020 season saw the OWL divide teams into two regions, North America and Asia, in an effort to reduce
lag due to online play. For the 2021 season, the twenty teams were divided into two regions, the East and West. Eight teams from China and South Korea competed in the East Region, while twelve teams from North America and Europe competed in the West Division. The majority of matches in the 2021 season were played online. Three live events were planned to be hosted by three teams in China: Hangzhou Spark in June, Shanghai Dragons in July, and Guangzhou Charge in August. All five China-based teams travelled to these events, while the three Korea-based teams played at the events remotely via the league's
cloud server. The Charge's homestand in August was cancelled, however, due to COVID-19 concerns. Additionally, the Dallas Fuel hosted a homestand in July at
Esports Stadium Arlington.
Midseason tournaments The league expanded upon the tournament format that was introduced in the 2020 season. Four standalone tournaments, the May Melee, June Joust, Summer Showdown, and Countdown Cup, were spread throughout the regular season with teams from both regions competing against each other. Hero pools, a system in which some
heroes are unplayable, were used in two of the four tournaments: the June Joust and Countdown Cup. For each tournament, teams played four weeks of regional qualifier matches. The top six teams from the West and the top four teams from the East advanced to regional knockout matches, and the top two teams from each region advanced from the knockouts to play in the interregional tournament. In an effort to minimize lag, the qualifying Western teams traveled to the
University of Hawaiʻi at Mānoa for each interregional tournament. The
internet service provider at the University of Hawaii was directly connected to a
cloud-based server in
Tokyo, Japan via an underwater sea cable, while the qualifying Eastern teams did not travel anywhere and connected to the Tokyo server from Asia. With this setup, the league was able to equal
latencies for all participating players with a "minimum-latency tool" developed by Activision.
Season playoffs Contrasted to previous seasons, where playoff seeding was determined by teams' win–loss record throughout the regular season, the league implemented a point system, called League Points, to determine regular season standings. Every win in the regular season earned a team one point. A first-, second-, or third-place finish in each midseason tournament earned the placing team an additional three, two, or one point, respectively. == Regular season ==
