I watched a lot of SC2 during WOL and I recently went to IEM San Jose. I was reminded of why I stopped watching. Koreans are completely impersonal. You can't even force yourself to become partial to them on any level other than their in game skills. As a foreigner, all the Koreans might as well be clones of each other. The language barrier is simply too much and it makes for a really boring spectator environment.
Ironically, this exact thing happened with women's professional golf with the dominance of Korean players whose sole focus was on winning. Fans became less interested in the game, sponsors were not happy about tournament winners being impersonal during press conferences, etc. It was a major factor (though not the only one) in the reduction of the tour schedule and overall decrease in prize money as well.
