I think that’s because dwarves are iconic warriors. Night Elves have sentinel armor. Blood Elves seem to be spell breaker.
It all seems to be what is the “iconic” class.
Human seems to be either warrior or paladin.
They kind of already have that with the Stromgarde warfront plate gear.
Yeah, Gnomes looks like Tinkers and Tauren look like warriors such as Cairne and Baine.
I want the Heritage Armor for Humans to be more like Varian Wrynn’s Armor. Very Lion like with a Hawk Shoulder piece.
