Communication is Key
As I have said before, Overwatch is first and foremost a team game. Communicating with your team is a key component to having success.
If you have a mic, don’t be afraid to use it to call out where an enemy is or how close you are to getting your ultimate. If you don’t have a mic, Blizzard has implemented a way to communicate without it by using their call-out system by pressing the down button.
By looking at different teammates or map objectives while pressing down will cause the call out to change slightly. For instance, while playing a support character, looking at a teammate that has low HP and saying “Need Healing” will notify them to come to you to receive health.
Alternatively, other communication lines such as “Group Up” will notify the team to group up near you so that you can launch a full out 6-man attack. This is especially useful for tank characters such as Reinhardt or Orisa.
Overall, teams that communicate effectively and listen to each other are far more likely to be successful and get a win rather than a team that doesn’t group up or uses callouts effectively.
