You can pair up this with farming Kurenai rep (Which can get some useful recipes and a Talbuk mount)
Each ogre gives 10-13 rep with Kurenai and they drop beads which can be handed in at Telaar, 500rep for 10.
There are also alot of greys drop there which sell for 1-2 gold each and good quality greens.
Voidspawns around Oshu'gun in Nagrand are great to farm on. They drop Oshu'gun crystal powder, Motes of Shadow, LOTS of greens, the occassional blue from a rare spawn around there, and 2-4 Netherweave Cloth.
