Checking MMO Champ front page this morning I see its been hotfixed to only work in Pandaria, even though the tooltip no longer has that written on it.

Little update to this item: It seems it longer makes u jump up 10 yards. Just the visual seems to be active.. tried relogging and reloading none worked. I think Blizz once againt ruins fun items.
Essence of the Breeze should now only usable while on the continent of Pandaria.
