So you mean team and cooperative FPSs and MMORPGs. This needs to be said. There’s a whole layer of games that have competitive regimes with 1-player ‘teams’ or even based around that with a little-to-no ability to get a benefit from talking. Fightings, racings, strategies, shooters with a deathmatch, chess lol. Without specifying it this opinion is just incorrect.

It’s not that unpopular when you get into higher ranks where you take on a challenge with a long-going group of players. In the lower ranks with randoms it’s probably harder to find a game where everyone’s connected, and also more agression and toxicity found in the chat. I liked playing support\tank roles in low level Overwatch (and DD had long queues anyway) without communication specifically because I had a joy of reading other people and the stakes were pretty low, but risking something more is weird.
