Well it certainly didn't help that he never even responded, actually lagged, and had an FB rank, Wasn't PandaPro also playing long after the guy was kicked?
As for the amount of people, what're they gonna do if a room is full? Leave, or make a new room, who's gonna be joining them..? Bringing in more people just like that wihtout actually knowing them is more likely to make other quit. (We've all seen how it's usually just the same 2-3 people who make rooms, and the others rather keep on fishing.)
