Another suggestion, sorry -
Right now the Mischievous Ghosts stone curse people when they are discovered, which makes sense from a mischief-making ghost standpoint, yus. Ranged jobs and stuff already have the upper-hand with this event because of the ghosts snapping off everywhere.
I'd like to suggest replacing that stone curse with something more minor like Chaos or Blind and instead stone cursing whoever kills the Mischievous Ghost for a little longer period of time. That way, whoever got a certificate will naturally get a bit of a time penalty before they can get another, allowing other players to find and try to kill other ghosts. If the point was to encourage KSing, then nevermind. Many of the rest of the players I've come across have been trying to play nice and letting stone cursed players be with their ghosts, if we can find them around the ghost (especially certain jobs), though... but I suppose it's our problem for doing so.
... That phrasing sound like an awkward romance.

Edit: Though using mercenaries can still bypass that... hrm.
Edit edit: A couple of us had a chat with evil thoughts about the ghosts proccing freeze/stone curse/sleep/etc./etc. while being attacked, magic immune, AND using teleport on a whim rather than snapping.
