Here now and have mixed feelings about FP+. I will say that what sucks for those off property and also for me on my first day since we bought our APs on arrival: If you do not have tickets prior to arrival or are staying off property, you have to do the dash to the FP+ stations and stand in lines, which are ugly. Upon the arrival of your turn, you are helped by a cast member with an iPad and your fast passes are selected and saved to your park ticket or magic band. Sine our new APs were not yet set up to our account, we did not have the option of changing our fast passes on the fly on our phones. I think this sis the same for off property guests as well. I think they have to go to kiosks or cast member manned stations to make changes. The stand by lines for the actual rides are probably shorter than the FP+ station lines.
Day 2-7, we have our tix set up and we can pre-book our FP+. So far, we have been successful in getting most of what we want, near the times we want by making them the night before and in one case, the day of, our visit to the park.
BUT, it is really slow here right now. I don't know how well the last minute planning will work during busy times.
Also, to answer the original question, on 1/22, paper fast passes were still being handed out at EPCOT. Don't know about today since we were at AK where they have already been removed.
