@Zatox I don't have a number for you, because I farm trying to get a Krono, then I get distracted by a shiny in the bazaar.
One of my problems has been that my Farming group does not get much, because they are farming in OT. Other than the occasional diamond, stuff in OT does not sell very well to the vendor.
Method 1, Vendor stuff
I feel like I get about 50K pp per day vendoring stuff, so maybe 40 days.
This is a lot faster in lower level zones, you get more kills but no experience, and no valuable drops.
I have gotten 2 ultra rare drops, but no one seems to be buying these.
Method 2,
/barter
Then there is barter, figure out which farmable items sell well in your area.
I did a /dga /mac bas.mac, and sold a ton of stuff on my guys, I got a lot of money.
This is a crap shoot. Depends where you are farming.
Method 3, Selling Bazaar (you need 1 krono first for this though).
I play during the day, and do the bazaar at night until I wake up.
Some days I wake up and I have 100K pp.
Some days I wake up and I have 0 pp, and I cry because no one bought my crap.
It is hard for me to tell what to sell here, I just end up with bags of junk no one buys. It is also different on every server.
Method 3.5, you could try to do that by saying /WTS in PoK or Guildlobby. I do not do this, I am not sure how effective it is.
