I agree with some of what you said. I've pretty much put off writing my feelings about FP+ on any thread b/c I know so many will disagree, and I also understand why it does and will work for some. And I think we all just have to realize we won't ever all agree one system was better than the other.
We used FP+ for the 2nd time in August. In Feb. it was ok; my main concern was getting on our favorite rides multiple times like we're used to, and for the most part we managed that (remember no 4th, 5th, etc. available then). In Aug. I thought it would be easier due to projected lower crowds and the ability to get more than 3.
Both trips we felt more rushed and locked in, locked in before we even started. Felt we were running around the parks more. Never felt that way with FP-. If we found a kiosk in Aug. with a long line, that sucked.
If we had decided to find a kiosk with a shorter line-what's the difference between doing that, or "running around getting paper FP's"? Don't see an improvement there. I don't want to plan my entire day 60 days out based on FP's. We used to go wherever we wanted to first and get a FP. BTMRR? Ride once, grab FP, do other rides in the general area until FP time. If we felt like doing PP first we'd do that, grab FP, general rides in the area until FP time. I could decide while waiting to go in. No running around, no deciding 2 months before trip

We also could (and did) ride TSMM at RD and grab a FP, then RnRc SB no wait; back to TSMM with FP, grab another FP for it and do RnRc again SB with barely a wait. No more of that...............
App rarely worked in Aug. so when we decided at dinner one night to change our park the next day, I couldn't change FP's in restaurant. Or walking around park afterwards. Or on bus. WiFi at resort wasn't good that night so couldn't change them until about midnight. Very annoying, when with old system we could have made our decision to switch parks and that was that. Yes, we could forego using our FP's and stand in line (and last week of Aug. wasn't that crowded but certain rides still had waits and it was HOT on line lol) but, we've always gone during relatively slow times and
don't wait on long lines. If waiting on long lines had been our experience on our first few trips, I don't know that we've have kept returning as often.
Last week of Aug. had lowest predicted crowds I believe since sometime in May??
However, arriving at EPCOT twice that week, at RD, TT and Soarin' were already out of FP's for the day. Same deal 3 mornings at RD at HS for TSMM. We weren't looking for these, but I noticed on the signs they thankfully now put up (which weren't there in Feb) before you wait on the kiosk lines. We didn't try for any 4th's except BTMRR one day, tried at 1:00 and got a 5, fine. Tried at 4:00 one day for a TOT and all that was left was Fantasmic and Muppets LOL

!! It was the day before Labor Day yes; but c'mon, really?? Finally, we got less repeat rides on the big ones in Aug. than in Feb. Not sure why. Well,
because SB lines were longer even though crowds were lower. And as I said, we don't wait on long lines b/c we've never had to.
Again let me say my experience with FP+ is that of a family used to going during non-busy times. Although, Black Friday 2012 we got FP's for Soarin' at 9:30 for 10:45, and at about 11:15 for 2:00. So there were more available later in the day then, than on Aug. 28th, 2014 at 9:00 with FP+
