Came up with an idea for an event a couple of days after MemoryLane's event suggestion thread closed and decided to post it anyway:
How about an event where every hour a random number between 2 and 10 is selected, and Purified Crystal drops are multiplied by that? One of the things everyone is always short on at the moment are PCs, so an event that makes farming those faster is one that will benefit everyone. By making it so the amount PC drops are multiplied by is random you would also encourage people to run dungeons outside of the normal times they do, since they might get better multipliers then. Aside from that it isn't the kind of event a few people can do entirely by themselves, so there is no worries that it will only benefit the extremely powerful players, like some current events do.
