Most people go through the same thing. They join thinking this game is going to be like TWO. It isn't.
People see the scores, and the credits won by the top players and they think they should score like that too, right off the bat. When they see how the game is setup, they realize this game is harder than they imagined. Most likely they don't even play real golf. Another possibility is there under-age accounts and can't handle the game play.
It's people always looking for the easy way into a game until they find out is out of their league.
