The animations changed a little during the days, the first two days I've played, running (Jogging) with the rifle would have him tilting the rifle a little bit sideways on low ready and running with his torso a little angled forward, now seems more like the wildlands jogging and sprint (Your video), I preferred the first one.
The speed in which you move when you walk and the speed of the walking animation definitely doesnt match. You are animated as walking slow but you move too fast, and it looks like sliding. Not good. and why not make use walk slower? people who want to walk dont care about their speed. They are NOT in a hurry. slow our walk down a notch to make the experience of walking better, because the sliding is distracting .
