Unfortunately, all of the top corps are composed of out of state people, who are usually 20/21 years old beacuse they want to be in it. It's mainly because of that that those corps are successful. Corps like Academy, who tries to keep everything local, are behind mostly because of that. It would even out the playing field a lot if, say, all of the corps had to have a certain percentage of local people in it. Look at Phantom, with maybe 5% of the corps (probably less, in fact) from in the area..... because the higher corps keep winning, people want to go to them, they get the cream of the crop, while the not top 12 corps are stuck.
