Stick it on the mog shop and be done with it. That's how the seasonal events seem to work nowadays. Miss that one opportunity to get it? Pay up a year later, or don't get it at all. At least they give you the option to get it if you miss it, RuneScape for example takes the approach of "You missed the event it comes from? Well too bad, you're never getting that item. Suck it up buttercup." - I daresay I prefer Square Enix's way of doing things. Though I agree the legacy tattoo etc, which were given as thanks from SE for supporting the game through the hellhole that was 1.0, should NEVER be put up for sale. And I speak as someone who never played 1.0 (started late 2.0, got to endgame early-mid 2.1).
