So I managed to hit exalted with both Cloud Serpents and Tillers this week. There was a point last week though, where I was essentially doing dailies with every single faction - Golden Lotus, Klaaxi, Cloud Serpents, Tillers, Anglers, Shado-Pan and August Celestials.
The entire process took about 3 hours, and generally netted me around 1,100 gold (just from quest rewards and grey items) as well as around 250 valor points per day. I was also collecting another 800-1,200g from selling all of the vegetables, fish and meat that I accumulated along the way.
Those numbers have dropped off significantly since I stopped running Cloud Serpent and Tillers after getting to exalted, but it's still a lengthy but rewarding process.
With the prices of cooking mats starting to drop on the auction house, I've decided to go ahead and start using my production to finish the other Ways rather than selling all of it. None of the others are really very close at this point, but I should make decent progress with my full 16 plot garden focused on it every day.
I've also been working on my hunter after dailies and dungeon runs are done, and he's sitting about half way to 87 and working his way through Valley of the Four Winds.
