Oftentimes all you need is to take a break from League. This might be 10 minutes between each match (not in queue), only one match each day, or you might even take a month or so off from playing the game at all. I even take a break when I'm on a winning streak, so as not to ruin it and end the night on a bad note!
During a game it can get pretty tense, and chatter from your teammates can get annoying. If anyone is being a jerk or just doing something to distract you, don't hesitate to Mute them; pings tend to be more than enough! Riot is also releasing a Ping muting feature so you can stop that pesky ??????.
