There are hidden treasures spread all over Pandaria rewarding gold, experience and grey trash items that sell for gold.
I've gotten the list with names of the items from another site. The only thing i did was to sum them up according to zone and the fastest route to visit all of the spawn points and create the images.
One other good thing to know, I've read that the treasures are character-phased. This means looting a treasure doesn't affect the treasures on other characters. They will still be there! (Going to confirm this tonight but as far as I've read other persons looting will not effect your treasure)
Done the run 2 times now over a time-lapse of about 2 days and received around 1500 gold and 15% exp (@ 89) each run.
I'm not at home right now so i still have a few items not listed by zone but i'll do that tonight. I'll also create a tomtom waypoint list when i get home.
Also, the names are clickable hyperlinks to the wowhead object page.
