Adobe needs to include IPTC information in the file INFO in Lr CC. This is the industry standard for file information and a requirement of most photo agencies, so why isn't it in CC? Cloud storage is great but without IPTC it's not of much use to those submitting to an agency.
When you have folder-based storage and cloud-based storage, they both want to be in charge of the files. It gets messy! But hopefully CC will add the features you need in time, as it gradually catches up with Classic, and then you'll be able to switch. There are ways to use both in tandem, but it gets a bit messy.
