There are several reasons why I am leaving. I have been playing almost every day for two years now. I no longer enjoy the game. An artery in my neck throbs when I play now. There is some mental block that is keeping me from being successful. There is no fun, it is just torture. Any passion I had for this game is gone. =(
You are going to face people who have been playing this game for over a decade. The competition is tough, but if you don't have any patience then maybe you should just play games casually from now on.
