So I have been looking around the site for the spot i farm primal fire and i havent seen one posted yet.
Skald is a supposedly one of the best spots to farm primal fires but like in http://www.mmowned.com/forums/wow-gu...p-350g-hr.html this guide, it tells you about how its over crowded and the low mob value of the imps and basilisks arent worth it. And the Throne of Element is just rediculous.
Since Fury of the Sunwell I noticed that the area north of Thrallmarr (Throne of Kil'Jaden) has the highest level of fire elementals so far. Unfortunately in the beginning too many people were farming for rep. Now that the SSO rep farming has come down this area is GREAT to farm for primal fire.
First get yourself there and go all the way to the eastern side. Here you wont find those elite Blood Elves in your way. On top of that there are about 10 fire elementals close enough together to all show up on track at one time and only 2 - 3 of the wrath dudes that patrol through. Farming here Produces and average amount of greens and grays and while they dont drop money, the primal fires sell for quite a bit on my server. In about an hour I farmed 10-11 primal fires which sold for 400g. Combined with the vendor trash and money from what mobs do drop it, thats about 450g i an hour.
Find your self a low population time on your server and go to town.
