If Halo 4 implemented the competitive skill rank system, fixed the killcam and playlist issues (in particular, implement lone wolves, team doubles, and team snipers), and maybe do some weapon tweaks, the level of complaining would go down and Halo 4 would be that much better of a game. The thing is, these are fixes that could be easily made in a short time period. I just don't understand why 343 won't go ahead and do it.
