Next worlds should be split into a different bracket system

NA vs EU and Korea vs China and "The last Region" (sorry but I forget which countries make up it) vs international teams. Then the winner or winners of each division make up the groups stage but only do best of 3 or 5 games 6 round robin. The pairs would be determined by score. first plays second third plays fourth, etc... then we go to quarter semi and finals. This way teams play statistically more even matches (not only would this help with team prep for harder opponents but it would give some sense of satisfaction to some teams who don't stand much of a chance against many of the teams, like TSM in their group this year or the whole world vs "The Korean Teams"). Think of this extra division as the preliminaries to the group stage.

Side note: We could see if NA > EU or if EU > NA if the two regions faced each other.
