Greetings. Walking is too fast. That is, when you bind a key to "Walk" and hold it down while pressing a direction key, you move too quickly. This ends up making your feet slide along the floor in what's commonly referred to as "skating". You can also see numerous(but not all) NPCs doing this.
A more appropriate walking speed might be similar to that of "aim" mode. Whoever's in charge of player and NPC movement might want to look into this.
Edit: On second thought, it seems that Aim mode's speed might be a bit fast as well. Now that the game is back up, I can see this for myself now. So when reviewing Walk speed, please make it slower than Aim mode speed.
