The Open Tournament is the thing that should be eliminated.  As it stands right now, the D1 Tournament is the loser tournament, sort of like the consolation championship because in order to get to the D1, you have to LOSE in the first round of the Open Tournament.  Then, on top of that, the losers are required to play consolation Open Tournament games for 3rd place which basically amounts to a meaningless game.    Just go back to D1 and D2 Tournaments.
