If you pay for the ticket you will get EQDs, EQMs with a class of service multiplier and anywhere from 15,000 to 30,000 RDMs.
I would echo what others say, if you find a saver award you are close to and need the miles maybe not a bad idea - but compare it to the cash price of the ticket plus the other potential benefits like qualifying for status and redeemable miles.
Agree

Really 
- searched the entire year from a couple of cities, and I could not find a single flight that had two CX F award space.
