Nagrand may be the best money making zone in the entire World of Warcraft!
Why you ask? Take a look....
Mining Route
Khorium
Adamantite
Fel Iron
Earth Elementals
Skinning Hotspot
Twilight Serpents - Cobra Scales
*Thick Clefthoof Leather drops all around zone from Clefthoofs, good gold there as well
Cloth & Coin
Sunspring Villagers - Extremely low health, good coin drops
Voidspawns - Easy kills, tons of Netherweave
Enchanting
Consult your factions Blade Merchant when in control of Halaa to purchase either
Avenging Blades @ 2g 21s - Thottbot World of Warcraft: Avenging Blades [Alliance]
or
The Sharp Cookie @ 2g 21s - Thottbot World of Warcraft: The Sharp Cookie [Horde]
And disenchant for what usually is 2x Greater Planar (occasional Large Prismatic)
Primals
Who needs to mention Elemental Plateau? Overfarmed for the most part
However there are Elementals of all shapes and sizes stretching the entire length of the zone, my favorite would be the
several types of air elementals, while a low drop rate, they are easy to kill.
Additional Notes:
*Engineers of course have gas clouds located randomly across the zone
*Do Ring of Law @ 70, don't bother with it before, the gold rewards are insane
*Farming mobs in Nagrand also yields Oshu'gun Crystal Powder Samples which can be turned in @ Halaa for Halaa Research Tokens, which gives u access to quite a few nice things.
*Theres always low levels of the opposite faction to grieve
