This might be seen as a rather redundant suggestion, since it's such a minuscule feature. As I am sure you all know, you get a little picture beside your name depending on whatever race and gender you are, most races and classes have a fairly straight forward option for this tiny feature. Male Pandaren, however utilize a rather obscure spell.

Look at that! When it's shrunk down so much it's hard to even tell what it is!
This is the Icon I suggest it should be changed to: achievement_worldevent_brewmaster
That's a lot more fitting, right? A picture of a Male Pandaren smiling!
I'm sorry for nitpicking over such a minuscule feature, but hey. I think it'd be a fitting little change.
