Now that we have a vanity system, I was thinking that maybe there should be an area added into the game world somewhere specifically for vanity drops. Want a costume from a previous event that you missed? why not have mobs in this area have a small chance to drop it? We could even make the costumes/vanity stuff sellable on the market boards for those who don't want to spend the time farming them.

Now, so as not to make it TOO EASY for people to get everything they want from this area, the monsters should start out very hard to solo, and gradually go to impossible to solo once you venture deep into the zone. Force cooperation between people for what they want, but at the same time, don't REQUIRE people to go in the zone if they don't want to. No gear drops, no gil, no crafting mats.. just vanity.
