The Scarf of Wondrous wit was already a reward once before. I remember grabbing one myself.

I think it's a good thing that more players are being granted access to neat rewards. There's already been a period of exclusivity/rarity for them after all. I spent eight million on the shiver emote, for example, back when it was first added to the game. Now it's available here and more people can enjoy it.

My only criticism is that maybe the scarf should be retired as a contest reward and made a permanent fixture of the Moogle events instead.
