Farming cloth is 100% useless these days. Nobody uses the old cloth and any money that could be made is small.

Kill the 4 rares in Tanaan- Doomroller, Deathtalon, Terrorfist, and Vengeance. I usually hang in the middle and wait for their announcement. Usually they'll all spawn within an hour. You can also use LFG which is much faster but I have ran into loot issues- IE: can't loot or corpse disappears. What you're after are Medallions of the Legion- worth 4-10k depending on the server. They always sell.

Run to Nagrand and kill the 3 new Highmaul rares. They drop 4k+ pets and apexis upgrades for baleful gear. The upgrades are also account bound and you can upgrade your team quickly to 695 gear.

Check for Demidos in Shadowmoon Valley- drops an expensive pet, also Oruumu in Talador drops a pet.

Run Throne of Thunder for the Pygmy Direhorn, gold , mounts.

They also say running the first part of Heart of Fear up to the first boss with luck potions is 4k an hr or something. This is just a straight up grind though killing and vendoring. I don't usually do it because I get too bored. But it's lucrative.

Kill Kazzak every week- sell the Felblight, enjoy the 705+ gear.
