So we are never going to see CSR in game or at least not for a long while. So how about a more of a social rank like they did in Halo 3. Each playlist would have it’s own separate rank based on military style ranks. This would be more like an experience rank in that playlist which in no way refers to a skill rank which 343 is against having in game. To level up though you would have to win the match to get credits towards the next rank. Quitters would lose credits.
This would at least give you something work towards after you get to 130.
If not that idea how about placing the Halo Reach ranks on top of the 130 once you get there. I like the other idea better but at least this would be something. SR-130 just comes too fast.
