Overwatch team has published a new developer update video dedicated to a new feature known as Avoid as Teammate. Game director Jeff Caplan discusses how this feature will help players control their game experience. It allows players to avoid up to two players as teammates for the period of seven days. The team will closely monitor how the feature performs and what possible side effects it can bring.
