After reading the source, it sounds like people are taking it out of context.
Here is what the source says (http://blogs.halowaypoint.com/Headlines/post/2013/01/23/The-Halo-Bulletin-12313.aspx):• You will have a unique CSR visible per playlist.
• Your highest CSR across all playlists will be promoted in the player profile on Halo Waypoint.
• CSR uses familiar 1-50 scale.
• When CSR launches, everyone will start with a fresh rating.
Just because your highest CSR is promoted on Waypoint, doesn't mean ranks aren't going to be displayed in game... I think people are being stupid and paranoid.
Yeah I don't see them doing that it would defeat the purpose. It would have more people off their game and checking waypoint which they do not actually prefer.
