I have not been able to find a way to access what you might call a leader board type page, does one even exist.
I guess an example would be like list the weapons based on most used not just from yourself but the whole xbox live community
another could be most used class or abilities in particular stuff like that.

If anyone knows where to find this stuff hit me up if not I would like to suggest its implemented =D
