Problems with avatar animations

How is it possible that a game with such good ideas has such horrible character animations. The avatar animation is not fluid the torso does not even move making the animation look and feel rigid.. This animations are to terrible and ugly.

The design in avatars body like a aliens, the part body are to flat, and its very funny but ugly and horrid when i just play and run or walking in the game.
The animation feels like a game from the 90's.

I compare this to Unreal Tournament. The latest unreal the animation feels more fluid and a bit more realistic granted understanding that it is a scifi world.

when someone walks or runs their whole body moves, As it stands now the torso of the character does not have realistic animations or the "bobbing" motion seen in other games. It sort of looks like if the avatar was tied to a stick and being moved on a straight line and only the legs and arm are free to move.
