Harvesting is badass for making gil. Hardly any NA players do it in my experience- go into Giddeus at off-hours for JP and you'll most likely be the only harvester, but after midnight EST you have to start elbowing people aside to get to the points. Mugwort is the big money result, last I looked it was about 25k per at the AH. But there are numerous other items that sell well and quickly- red moko grass, saruta cotton, crawler cocoons, herb/veg/grain seeds, etc. I'd estimate about 100-150K per hour harvesting on average, possibly more. Combining harvesting with levelling clothcraft is also a smart move, it's nice to be able to smoosh the everpresent near-worthless flax flowers into linen.
I should also mention that I snagged Hoo Mjuu twice while harvesting, just happened to be running through there when he popped and outclaimed the campers, heh. No drop though.
I have no problem disclosing this information because now that I'm past sweet rice cakes in cooking my harvesting days are probably over, lol. It's great gil, but boring as hell. :wink:
