Guys, try running in real life, outside your house on your... lawn or something. Then notice how much your view is just murdered by the excessive bobbing of your head (if this doesn't work, try harder.)
Now I notice when sprinting within the game itself, it seems like you're just sliding very fast. I feel that if your view bobs in a way whilst sprinting ingame, it would feel more like sprinting and also provide some immersion factors.
