When I've played I've turned off comms, but kind of hard to ignore the aim bots and chat if you're at least trying to work with your team.
If you're upset at the idea of people yelling at you then you just have weak mental and need to improve. Alternatively, you just might not enjoy that kind of ultra-competitive game and should find another game to play. Either one is absolutely fine.
I've watched competitive games and the teammates are in no way distracting and yelling at their teams. They are doing their most to work cooperatively and even minimize distractions by only speaking up when it contributes.
For me at least it stops being fun if people are legitimately upset about what's happening versus people enjoying playing the game together. In general esports seems to have really turned this dial for games in general towards competitive, with a shift in focus from moment to moment gameplay being fun to climbing ELO and completing battlepass tiers.
For what it's worth if this sounds like scrub salt I was GM in Overwatch for the first few seasons (back then people actually talked too) so I get the appeal, but long term it just feels like a second job after a while.
The small funny moments of friendship you might get from that is drowned underneath a torrent of racism, sexism, spite, anger, and random nonsense that is draining and, maybe more importantly, seriously distracting. Nearly every serious player I know will full mute even their friends during intense moments requiring mechanical skill.
If you are 30+ and play competitive games to meet new people you are in the wrong place.
