Feel free to take a break from LoL if you no longer enjoy it.

I can't enjoy it anymore. Game balance, players' behavior, and connection quality are driving me away. I loved this game so much that forced me to stayed for a very long time. However, I feel it's time to take a break from it. Now I am really relaxed to enjoy other stuff in my life.

If you don't find it fun anymore, take a break. Riot may fix all the problems someday.
