This profile for GB2 covers Jade Forest, Valley of Four Winds, Kun-Lai Summit, Townlong Steppes, and Dread Wastes. I made it by simply throwing together all the hotspots, vendors, mailboxes, and blackspots from 5 separate profiles. It gathers every herb and ore in Pandaria, I believe.
It wastes a lot of time fighting in Townlong Steppes and Dread Wastes, and I died twice in 4 hours on a 445 ilevel Guardian Druid with the crappy Singular Guardian combat profile. In 4 hours, it did about 550 nodes, and killed about 200 mobs. It isn't polished and it can be annoying at times, but it might be useful to you. Test it out and tell me what you think.
