I know Ghosts' stats, game history and clan management is not available on Elite on a computer, and only avaiable on a phone app. http://community.callofduty.com/thread/200796759#.UpOFSeJ_LXU
But why not, it's no much easier on a computer.
/agree having an app that isn't available on the pc is major step backwards but saying that
if you have a win8 pc you can use the win version of the app on your pc
there are also ways to use the app on pc but we are not allowed to explain on here
Thanks for posting! I agree that ELITE was a convenient hub for players to manage their BLOPS, MW3 and BLOPS 2 accounts. However, I do not have information on why Ghosts is only available via the mobile app at the moment as the decision was made by developers. The app is super convenient though for checking my Ghosts stats and managing my clan on the go :].
