Throne of elements in nagrand?
Cause right now im farming in Shadowmoon Valley, Place called Legion Hold. Demon guys there (can be pick pocketed). They drop Marks Of Segares (sell for about 1-1.5g each) Fel Armaments (17-25g) Greens (I vendor) Maybe an occasional blue ( Auction House them of course) Not to mention they drop some where around (7-25s each). Maybe this helps i hope.
P.S. Getting the Fel Armaments requires pure luck. At one minute i can get 4 in a row, then i will farm there for another 2 hours and get none. Just be patient.
Hope This Helps
