Getting competitive is fine. But please remember that this is a game.
I love the entire league of legends community. I believe that some of us can have bad days/games and that will effect our behavior. But some times its unacceptable.
In one of my matches today, a person constantly told me that i was "fucking horrible" and kept complaining the entire match about how i was doing "so bad". This wasnt even true, and it would still be unacceptable even if it was.
Summoners. Please remember that this is a game and try to calm yourself down before you type in the chat. GLHF in all of your future games.
