Maybe after you are done with you Dailies in HF and want some extra cash.. As a lvl 70 will be easy to get it.
Right in the middle of Hellfire Penninsula, there is a Elite mob named 'Hand of Kargath'(around 48,50)he is a 63 elite, and has 2 other mobs next to him 'Shattered Hand Berserker' - these mobs respawn INSTANTLY upon death!
From this you can get about 45g-50g if you decide to farm it for an hour or so and about 5-6 stacks of Netherweave cloth and another 5-6 stacks of Runecloth. Very easy grind just by standing in the same spot and killing over and over and over.(For rogues he has a chance to drop rare gems from Pick Pocket)
As a lvl 70 you'll just be doin this alone and getting some extra cash not much but can help with some repairs or something..
Hope this helps some ppl. (maybe not a big guide but sometimes is useful for those times you find your self bored flying in outlands lol)
