I feel that having more events that are provided by staff would created an overall more fun experience for all players of a certain game mode. Back in the old days of Skyblock, I remember always looking forward to drop parties and having the chance to receive an xDacon head and other staff heads to create memorials for them. I feel that this would have a very positive impact and would be a very easy thing to set up as all that is needed is a chest full of items and a bunch of people jumping like crazy :)
