Firstly
People dont do anything when talking. they stand there like robots. cant someone make them move like real people? use hand movements, look away from the targets at times, act defensive, act aggressive, act sarcastic, act bored, act humorous!!
secondly the spells and weapons. Why the hell do i put my firey hand right up to my face in first person. Why dont enemies have loads of idle animations or animate in ways that look comfortable?
and dont you think a lot of creatures could have more behaviors? Look at monster hunter for instance, those dragons are all you fight so they have so many unique ways to attack you.
