Still have CC suite here at work as well, but almost exclusively use Designer/Photo at the office (as its mostly for me and 1-2 office mates) and at home. As others have said, I really miss nothing except Ai vector warping tools, but I rarely use those anyway. Only times I've had to switch to Ai is for logo output or assets for motion graphics, just to achieve highest compatibility with someone outside.
