shhhh... don't forget there are the types that claim they never waited more than 15mins for anything ever
I know I've been one of the ones who said that -- but only for one trip! It was for a trip during a low crowd season (early October). We were at a park at rope drop every day and used Fastpasses for anything with a posted wait time over 20 minutes (and thanks to the low crowd season, only headliners had such lines).
Before that, we always went during Easter break, and the majority of those visits were pre-Fastpass. We arrived at rope drop every day but fully understood that by mid-day, we'd be waiting 30 minutes or more for just about everything (I think the longest we ever waited was 90 minutes, for Soarin', but we didn't bat an eye at waiting 45 minutes or more for a headliner). That was totally fine by us, because we'd known "what we signed up for" before we ever left home.
The reason people like me cry "bummer!" when we hear about FP+ is not because it's going to kill us to stand in line, but because
nobody likes to backslide.
No one wants to have to adjust their expectations in a downward direction. Imagine if tomorrow, the U.S. government decided that it wasn't fair that people who drive to work get there faster than people who take an Amish buggy for religious reasons, so they abolished cars and we were all required to get around in horse-drawn carriages again. It's not that the result is inherently bad -- it puts everyone on more equal footing and everybody still gets where they want to go -- but it's making the lives of car drivers (or to apply the example, savvy Disney tourists) far more difficult and their movements less efficient than before.
That being said, we will lower our expectations and raise our ideas of what is an "unreasonable" wait in line, and adjust to it as we did before. We won't stand in lines whining. We'll take it on the chin and move on. It's just a shame that our WDW experience has to backslide instead of improving.
