Hitting exalted with all the major factions was a feat I accomplished on my (then) main back in 2007 or so…now I need to do it again on an actual Dwarf for the heritage armor.
Dwarf Bronzebeard Heritage Armor is earned upon reaching 50, hitting Exalted with Ironforge, and completing a short questline on the history of the Dwarves. This can only be transmogged by Dwarves.
