Not at all. I just use wow to keep myself interested when i am doing things that most people could not do for long periods of time. Because of what i do, there are a lot of reperative things that most people would find boring. What gives me such an edge is that i can force myself to continue to work on whatever i am doing because i am keeping myself entertained in my mind.
There are times when i need to shut wow out, like when i'm working or doing something for school, but like i said it's all about control.
Yes WoW is also mental, and at first i had trouble paying attention and my mind would drift off. I even went through the phase where you have dreams about yourself playing wow
They all passed, and i'm settled in a very comfortable setting where i can be really good at a game, but it doesn't control my life.
But wow is goign to end soon, i'm guessing cata will be the last major update, including major patches, and will slowly die, while blizzard switches their development power to the next project.
I mean tell me that WoW hasn't started to chafe. It is great, but after a while it just becomes too much, and to predictable. It's been out for so long, that certain people are so good that it's just sickening, and theres really no chance you can just enter a scene and expect to be concidered great. I was lucky enough to have started playing in beta, but whenever i like took a week or two week break from wow, i would come back outdated and having to go to my guilds second string raids.
It's hard to play wow without having to play it a lot.
That's why i'm getting into LoL, it's a pickup and put down kind of game.
