I'd like to see a really nerdy human female wizard. Not an 'I'll kill you all with fire!', not 'I will unlock the Dark Secrets bwahahah!!', and not some brazen 'Let's make sexy illusions and roll about on Tenser's Floating waterbed'.
I want see a scholar, a mousy wizard who wears glasses and has ink stains on her sleeves. A companion who can be romanced but who you struggle to take beyond kissing and cuddling.
Now that would be a first in any RPG so far as I can see.
There was Merrill in Dragon Age 2: she was pretty much like that. Neither "I am teh pwn and will turn your intestines into a plague of frogs!" like Morrigan nor the stereotypical "I cast a spell and all my clothes fell off", just someone who was socially awkward, bookish and tended to obsess over inappropriate stuff.
