Overwatch player quality kinda dips on the weekend. Not talking about skill, but about tilted, raging people who get mad at pretty much anything.
I thinkk 1/3 of my games had a leaver, sometimes on my team, sometimes on the enemy team. At least on Dota you have a report system which works, on Overwatch only god knows what it takes for someone to be banned from competitive and he can still play Quick Play, which honestly I don't recommend.
