Excuse me if could not make out what you are trying to say. If it is about the availability of Frequency Capping, I can confirm that it's available still. But with Display Network Campaigns only.
You need to go to the Advanced Settings to access it. More can be found on this URL -
If you are referring to the removal of the "reach and frequency" report from the Dimensions tab which occurred in January 2015 , this data is now available under the campaign tab.
"Starting the week of January 28th, reach and frequency metrics will only be accessible from the ‘Campaigns’ tab. This means that the reach and frequency reports currently accessed or scheduled in the ‘Dimensions’ tab will no longer be generated after this date."
