I say this in every thread like this and I'll say it again: the outfits and mounts that we get (that are not tied to seasonal events/fanfests) are from the China and/or Korean version of FFXIV, which is run differently than ours. They have to pay for these items over there, we requested them, so now we're getting them, and we have to pay as well.

The only thing I wish they would do differently is allow the seasonal event items to be purchasable ingame once a year when that event comes around again. If you missed the event and don't want to wait a whole year, then buy it off the Mogstation. If not, then just get it when it comes around again.
