Thanks for trying. We're install CC2014 packages. We've tried combined pkgs and single pkgs and have had issues with both of them. The single pkgs seem to work a little better as at least then we know where failures happen, but they are not consistent. Using RUM is still the only real way to go for us here, at least once we've got a base installed. It mostly does what it's supposed to do -- even though sometimes it takes 3-4 attempts for some pkgs to actually update properly. We have also had instances where some machines just will not run certain updates -- which usually requires us to reimage the whole machine.
It was so much easier with CS6 CC has been a royal pain for us to date.
