not to mention a cleric buffing and healing a couple of teams to help them survive the toughest monster. i'd call it upmost unfair, but meh - luckily he didnt managed to ruin the event, at least the fun factor of it.
sending ppl to prison worked well imo. they could improve this a little, by stating the rules before the event and then just sending offenders to prison after the first warning or so. no need to interrupt the event for long minutes, just get rid of them. maybe a second GM could take care of sending people to prison for the time of the event - a couple of days, depending on what they did
i was quite amazed how hard it was to make even about 50-100 people to stand on the stairs. not sure if i hadnt just burnt them all after 15 mins

so props to Dakkon, he made a good job so i had my fun for sure
