So you are basing your opinion on people who do nothing but play games. Sorry to disappoint but those people are not the ones that will keep this game going, people with money will and they are not 'no-lifer trainers'.
It is only 'easy' if you pump hour upon hour on this game and do nothing else, I agree, but most people are not like that.
The only thing that annoys me is the server being full when I come home from work :( Oh, and not being able to order the moves that my Pokemon have grinds my OCD gears.
