I think it would be very interesting to see teams fly out to Korea like a month before worlds and bootcamp to get practice against Korean teams. A team like Alliance, Cloud 9, or TSM could learn a lot from the top Koreans. I think thats why Season 2 worlds was closer then Season 3. Teams like TPA and CLG.eu learned from the Koreans at the time and I think that modern teams need the same sort of environment.
