Events are rarely hosted nowadays. Only one or two admins host a day, even though every admin receives 5 event coins to distribute everyday. A lot of players, myself included, would enjoy more events.
I also believe that auctions should be hosted more often. The rare times that auctions are hosted, it's very early in the morning or very late at night (in the United States).
An auction bot would also be nice, selling freebie items every 5 minutes and messaging through pms like the event bot. And, like the event bot, an event coin should be hosted every hour.
I'd like to see improvements in the occurrences of events and auctions mostly.
