Clean Sweep is the worst This is worst than dueling or Full Marks. In Dueling I actually have a chance. FM we have no chance because of Bots. Clean Sweep has the illusion of a chance to get the big prizes because there is such a slow timer and  fast paced Quidditch rounds, it is so unfair it should be considered torture. I mean, at least in the big matches in Quidditch we have a chance to get a damn perfect game, but here? Absolutely no chance. In other words, Clean Sweep is fucking bullshit.
