You can find a lot of Shienor Talonites & Sorcerers at Veil Reskk and Veil Skith in Terokkar Forest. These creatures are in the low 60’s and has a drop rate of 50% for Arakkoa Feathers.
These feathers can either be used for Lower City reputation (The Outcasts Plight and More Feathers) or can be sold at the AH for nearly 1.5G-ish each. You can also fit 250 of them in a stack allowing you to farm there for a long time if you’re level 70.
Both these mobs also have a 30%-ish drop rate for Rune Cloth and Netherweave Cloth.
