As leatherman says, It's so fucking deep. You cannot get the screens close enough to your eyes without possibly cranking the headset incredibly tight. Taking the faceplate off gives a much higher FOV and removes the huge pressure from the front of your face (from the super tight face-plate). 

The foam also gets incredibly itchy very quickly and the design is such that you have to loosen and move the headset off your face in order to actually scratch, which I need to do constantly because without the faceplate, all the weight is handled in the halo headstrap.
