Character Personality type inclusion?

[DynamoAce]

So this is a little idea that came to me from one of my previous threads on emotes.
We already have some great customization for Character appearance, down to their appearance, face, voice, idle poses, sitting poses, etc. When it comes to that you could say that can give off a personality type of a character.

What are your thoughts on personality types the way we do for our retainers? While we don't really get our own speech bubbles of text, maybe something to do with the way our characters carry themselves?

To clarify I suppose through talking animations, walking/running animations, their usual face expression. Most of faces offered are usually straight faced, or very..angry looking. Maybe if we get an option of having the choice of their default expression being a smile (Not as exaggerated as when you use the emote), cocky smirk, somber, etc.
