I don't see this as much of a complaint, I think he is just stating that in order for halo 4 to be continued on the Pro Circuit, or any other halos for that matter, there needs to be ranking system that is visible. Like someone said earlier if it's not visible there will be still be no incentive to use teamwork and win because it's invisible anyway.
I didn't play halo reach as much as I did Halo 3, but I did play it a decent amount of time, and I had no idea BPR existed for a long time. No one ever talked about it and obviously didn't care to ask what mine was, and honestly I don't really see the difference between the two. Hopefully this new ranking system system evolves halo for the better.
