Scoreboard would be better off decoupled from the old tab screen. It clutters the screen with unnecessary information, it looks bland and ugly and gives reason for toxicity and blaming your teammates, something Overwatch players do well on their own.
It would be better off being left as optional screen you can check after the game is over, if you need additional information about if you need to say, avoid someone. That and if we’re making it about individual performance, then teamwork is already dead and Overwatch as we know it is dead if it lacks teamwork.
We don’t need players to exclaim even more how much they’re diffing people.
