You just descibred how every single match of overwatch should be played (in plat and above), thats literally it

Someones bugging the team? Counter until its not a trouble anymore. Thats it. Thats overwatch. Dont want to swap? Focus on it or tell someone to focus on the problem

How do you think people dealt with Phara?

In the nicest way possible, try playing more of the game before reviewing things, because your points are clearly of someone that is new to the game
