A moment of levity: please imagine what happens to an organization as international and diverse as Overwatch (either original or post-recall) during the World Cup.
Alliances are formed. Pacts are made. Elaborate flowcharts are designed to determine who you cheer for after your own country is eliminated based on historical real-world grudges, historical football grudges, and your own grudges against people from those countries on base.
During the entire tenure of Overwatch, the US makes it out of the group stage exactly once. Morrison and Reyes become utterly fucking insufferable, and then stop speaking to Reinhardt for a full week after Germany knocks them out.
