I think a reasonable game could be played with those rules, given how quickly goals are scored and how hard it is supposed to be to catch the snitch. It’s just that it didn’t make sense at all that Krum was celebrated. Catching the snitch was worse than scoring an own goal in soccer because it directly and immediately caused his team to lose the match. The rioting of the death eaters after the match is understandable, but the way everyone else behaved towards this obvious fraud is not. The Ministry should have started a match fixing investigation.
