In any given region, there would be some fans going to pretty much all the shows and sleeping overnight, so often the same people got up front. I didn`t care because I don`t need to be front row and consider spending the night in line a waste of time. But behind those maybe 10-20 people, the crowd differed at every show, and it's not like the same 300 people were in the Heart at every show (although at the end of the first leg a lot of the people in the GA line had been there at least once already). But for most shows if you got there before noon you could get into the Heart.
So the problem was real, but not as bad as some people say, IMO. I also understand that the band would not want to see the same people up front, and I think it's nice to try to find a way to give a greater chance to more fans. But this system creates WAY more problems than it solves, and seems to make most fans bitter. Also, I don't think it solves the problems of the super-hard-core going to tons of shows and sleeping overnight, because these people will end-up monopolizing the front of the ellipse. But now there is even less possibilities of a good spot for the majority of fans who are willing to line-up for part of the day for one or two shows.
