Aldor : Here the things goes bad! If you want an exalted here, you must farm fair enought: you will need "Fel Armament", and you can farm them in Shadowmoon Valley for being precise, at Legion Hold ( west, near the entrace from Terrokar). You will need from neutral to exalted 110 Fel arm. ( not counting perks of any type)
