Female Lord (Lady)
I know this is a long shot.. and would require model and sound work.
But I would really recommend being able to play as either a Lord OR Lady for at least the Human and Elf factions. The variety - would add to the experience and make the character feel a little more personal.
As is - it's supposed to be you, right? So it should be the most customizable unit in the game.. that and maybe the dragons, heh.
