I genuinely don't understand why anyone has chat or coms on

We all just play videogames to have fun right? What's the point if it's constantly making you frustrated and sad or feel belittled? Who cares if you're silver III as long as you're having fun? You're probably having a way better time than the diamond II guy who's always being called slurs and told he's trash. You have no obligation to win or make your teammates happy. You play videogames for you, to have fun, to feel happy. Turn off coms if they don't do that.
