VR versus normal players doesn't appear to be very possible anyway considering it appears to mod base files, so unless people had the mod installed and didn't use the VR equipment necessary, it would be splitting communities in the first place.
Besides, there's much more interesting things you could do in VR vs VR matches that controller users can't necessarily do, such as being able to, in a sense, blind fire(fire a gun without looking, ex. from a corner, with your gun sticking out to shoot). It really opens up new tactics and adds variety.
