It's too bad we didn't run this game differently. Have each person cast a vote, or maybe five ranked votes for the worst class, and then get rid of the bottom five classes each round. This could be done each day at a certain time or so. You could widdle them down pretty quick that way.
Also, you could run it where you rank five good and five bad classes, that way, in the second round, ten classes would be removed: the top five that are immune, and the bottom five that got nixed.
