Do the Ancient Heirloom Armor Casing and the Ancient Heirloom Scabbard require that the toon applying the effect be level 100? Put another way, can a level 90 toon upgrade a lvl 60 heirloom to max to level 90?
Also, are the upgrades from 90-100 worth it or does Garrisons or questing provide better stuff? To what ilvl is it equivalent?
