I think animations like this would be almost necessary if they're going the 3d animation route. It would be really awkward if they just kinda stand there during every event. Instead of the art, we get them acting out stuff. If they're drinking, put a mug in their hand. If they're on a precarious balcony, show the character standing by a balcony rail. In battle, do a little sword play.
They don't need to be complicated, but a few seconds animation based on the event would be nice .
