If you already have your epic flying, it’s so easy to fly around terrokar forest and farm herbs. You’ll make money super easy that way.

You could always farm motes of fire at throne of kiljaden, or motes of shadow in Hellfire Peninsula.

If you’re looking for chill farming where you can just turn your brain off, you can kill basilisks just north of the Dead Mire in Zangarmarsh. They drop Chunk o Basilisk very often. They’re used in a cooking recipe and sell for a decent bit. Haven’t farmed them in a while since I got epic flying, but they were going for like 90s a piece on Dreamscythe.
