I'm going to agree with Mr. Beanz here, especially the part about boxes and bots leveling up faster than they normally would due to XP boosts. I also have more selfish reasons to end the event as scheduled. My physical location at the moment presents obstacles to the length of time I can be logged in and I'm sure that I'm not the only player with this situation. By offering these types of events randomly with short durations throughout the year allows more players to be able to attend the event without falling too far behind the general population of the server when they cannot effectively attend previous events. Basically, misery loves company.
