And lets not leave out white hair for the undead.
We have some really out there colors (green especially) but no white.
And give us a long-stringy style as well.
I want beards for Troll males, and longer beards for all races. I'm talking Gandalf beards; not silly mutton chops/goatees.
As for hair styles, i'm hoping that with the model updates they'll give all races the Worgen/Pandaren-style hair with movement physics.

I would welcome huge amount of hairstyles just for having options. Not that i personally like afros or any "cool" hairstyles, ie. i would prefer my draenei having "normal" ponytail, not some teenage whore belf one. I want practical and non-flashy hairstyles.
I don't like: raids, grouping, warcraft movie, doomhammer
I hate: orcs, especially thrall, pvp, sylvanas, legacy server whiners
I like: ???
