I just noticed, if you look at your character in the character select screen, they have idle animations. You can see them breathing, the shoulders going up and down as well as blinking. Compare the difference between your character on the select screen and ingame.
I do play other games in which you can buy the animation to suit your character. So if you have a Jedi and you want him to be meditative hands crossed in front of him, or maybe an emo sith. A bounty hunter who is looking a little shifty observing his surroundings etc...
