There IS a problem with support. Too much NAH in this community. I can think of a lot of netplayers who, if they showed up to majors and travelled, would raise the average skill level of a tourney a fuckton.
Last year's Evo didn't have representation from every region either. It was basically PNW/Cali/Texas (and a small amount of EC). You can tell from this website that there are some strongholds from BB across the nation, but sad to say, this game just isn't serious enough for people to travel.
