Firstly I'll admit to not reading the entire article but I wanted to give my two cents on the subject.
I also took a rather long break and then returned with new positive energy and ready to work together for the team. But after only two matches my will to live was diminished. 4-5 dps each round, rude/insulting people in voice chat and generally no teamwork.
I used to be mid to high diamond but am now hardstuck in plat.
The community in OW wears me down and I refuse to play it alone, the odds of ending up with 5 idiots are higher than they should, there are great, polite people out there sure, but they never seem to be on my team.
I will definitely keep playing it, it's just sad that a video game tears me down the way it does because of a rotten/toxic community.
