The Overwatch community is always evolving alongside the game, becoming more in tune with the game’s intricacies and discovering and sharing new high-level approaches to play. Today we’re introducing a brand-new Role Queue system to help ensure Overwatch matches continue to be fair and fun well into the future, and create an environment that fosters teamwork and encourages players to bring their very best to every match.
Currently in Quick Play and Competitive Play, a lot of important decision-making happens in the 40 seconds before a match even begins, as everyone selects their heroes and responds to others’ role choices. It’s not uncommon for players—who may all have different goals and play styles—to feel tension, pressure, disappointment, or even hostility as a team composition comes together. The Role Queue system is designed to help take the edge off this process, ultimately leading to matches that feel fairer and more fun, where players are in roles that they want to be in.
