The Best Tip In Solo Queue
Stop constantly badgering your teammates for making mistakes. This helps no one, all you are doing is making them more upset and impacting their game play negatively.
You do realize that there is a person behind that champion, right? Everyone has feelings, even you. Just because you are behind a monitor doesn't mean you should crap talk them because of your own insecurities.
Instead of typing that negative comment towards that ally of yours, backspace what you are about to say and just the play damn game.
