They did a great job on the game in many areas..
What i'm most displeased about is the announcement that the CSR ( Competitive Skill Rank: Which is 1 thru 50 and will be similar to the HAlo 3 rank ) will only be shown in waypoint (app or pc ) or smartglass (app on iphone and droid) when it releases in April..
This means the best way to do this is to download smartglass and you'll see your rank move up or down plus it'll have a place to type in gamertags of people you're playing with and against..
I'm a long time fan and I believe ITS ABSOLUTELY LUDICROUS that a system found IN THE GAME ( meant to track and keep rank ) can't ONLY BE VIEWED OUTSIDE THE GAME ! HAHA
This system has no effect on the current Progressive Ranking system in Halo 4 which is similar to COD's Progressive Ranking..
