Overwatch is an extremely diverse game. With over 30 million players, some are bound to be salty.
Overwatch is an awesome game, I can't deny that, but sometimes the people that play it aren't so great. Interacting with other players is just a part of the game, it can't really be avoided. Competitive play almost makes it mandatory to talk and strategize with your teammates, and if you don't then you'll probably lose. Quick Play can be a lot less chaotic, but there are still people that will throw a fit over a video game.
But why do these people get so angry? Well, that's something I'll never understand fully. Video games are here for us have fun and make friends. My theory is that it's because they feel like the rest of their life is out of control, so they want to control everything they can. They make a safe space out of video games, and when that goes wrong, they try their hardest to gain control again by giving you or your teammates a hard time. Or maybe they just had a bad day. I'll never know.
Moral of the story? Don't be that guy. You know, the person that ruins everyone's experience. The person that acts less mature than a child. Overwatch is a masterpiece of a game that we can all enjoy together, so long as people don't ruin it.
