So I'm really not a fan of the sensitivity while running, its a snails pace compared to what my actual sensitivity is set to. Add to that the tiny FoV while in first person and motion blur on X1 makes taking cover awkward. The only thing you can do while running is jump, at least make the sensitivity scale with my settings please. Its really annoying when I get rushed strong ai and botch taking cover cause the slow turning speed.
I personally really liked the running component. When the game goes live try sliding like a lot, to me it feels like I'm doing 90 degree turns faster then when walking. Sprint from safe zone to safe zone and slide early and often it just may throw off their headshot and it definitely helps with corners and doors.
