1) Update the sprint animations, they are dreadful.
2) The ability to toggle the camera between over shoulder or directly behind the player.
3) Jumping looks like you are falling very slowly on the way down. Needs tweaking (not to be confused with Twerking).
4) When auto loot is turned on, it would be nice to see what we are auto looting.
5) If auto loot is not turned on, the ability to loot with the same key. So be able to bind open bags with E and loot with E.
These things are minor. But they were noticeable to the game play experience.
Cheers.
