This change makes the game uncomfortable, I am aware the games client/server tracking at speeds makes it hard to track targets and I want to see this improved also I am aware you can still TURBO while crouched, but its not comfortable, smooth and doesn't feel right. .46 was doing nicely for movement improvements, please revert back and try another not so harsh approach.
First time I tried .47 experimental, I played for a short while got fed up and immediately went looking for a "fix" because I it just did not feel right (and I did play for about 2 hours).
