So in this expansion, Blizzard put in a LOT of effort on the "Class Fantasy". With a bit of a mixed results - sometimes it worked, sometimes it doesn't. The armory was updated now to display the Order Hall image behind your character, rather than the race image (Death Knights were an exception I think on the Armory though?)
I'm personally more on the side of that I am not too fond of the Class Fantasy a whole lot. Not a big fan of my Blood Knight to be in the paladin Order Hall (Despite Blizzard wanting them to be just standard paladins, rather than being more unique) and preferred the race bit. Pretty sure I read someone not too happy with his dwarf hunter at an elven looking lodge.
So, my question is: What do you value the most for your character, your Faction - you Race - your Class? I do not mean just the whole background-image part, but was just an example.
