I'm looking for one, anyone got anyidea if there is one? Like the Argus sign for Draeneis, the winged helm for blood elves or the silver hand for humans/dwarves
Don't think there is one. Most transmog and the like I've seen just use the Thunder Bluff tabard.
Personally I like how T9 looks, it still has that "tribal" feel but it looks beefy enough (pun intended).
