Wow, it pretty baggered me that you got no additional daily quests with the Shado-Pan and Celestials at honored and revered, but it also seems that there's no final quest for the Celestials when you hit Exalted, unlike all the other factions on Pandaria.
Pretty dissappointing, because I certainly wasnt aiming for exalted for another cloud serpent mount, which also costs 9k gold.
