it's competitive, the very nature of the game type is going to bring on some stress and anxiety. best way to stay calm, is to always focus on what you should be doing and how you can do it better. people that tell you to just avoid team chat are complete idiots. it's a team based game, use voice chat!!!! sometimes you will get ragers and flamers, but you gotta realize that you'll probably never talk to them again so who gives a shit what they say unless it's relevant to the team fight. and if you start to feel yourself getting upset, go play a couple qp games or just log off for a little bit and calm yourself before getting back into comp. but seriously, just focus on yourself, and call out enemy positions. usually even of no one else is talking, they can usually still hear you. and most people are too shy or scared to be the shot caller. so if you take that role upon yourself, you'll see that people do actually listen, not everyone obviously, but a lot of people will listen and you'll win more often. because a lot of people don t understand what feeding enemy ults mean, and they think if I could just hold off until the team gets back. and by the time we're back they're dead and the cycle continues. so use voice coms, evaluate your own performance and remember, it is only a game, but competitive is meant to be competitive so go in with every intention of winning and working with your team. you might be surprised
