Nope.
Recently returned from a short 3-day trip booked at only 30 days out. I was able to get every FP I wanted. FOP (on day #2 then Navi same-day, then another FOP same-day), FEA (then Soarin’ and TT same-day), 7DMT, etc., etc.
I think those are willing to spend a little time planning will still be able to enjoy the parks just as they are now. This is a luxury add-on IMO. Not a necessity by any means. But a very convenient offering for those that find it appealing.
You went during a very quiet period for Disney World, and both before the CL rooms and Disney Neighbor hotels started grabbing all that fastpasses. Essentially, you were able to grab a few M+M's out of a bowl that only a few people had already passed by. With these changes, the bag of M+M's will first be passed to CL people, then all around the 60 day people, then to the 30 day people, and will then be dumped into the 'day of' bowl. That's a lot more passing around first. (By the way, I'm really in the mood for M+M's right now...)
