I agree with you that when you're in the line you don't think so much about the effect and I knew that was the place you were coming from when you made your comment about EP. Part of my viewpoint was about how not every attraction has EP and even if it did IF Universal was going off of past ways of doing it they put it on attractions as time goes on. So the net effect is when EP is added onto an attraction the Standby line gets longer and that can have a ripple effect to attractions not under EP (which to be fair since 2017 has been very limited but pre summer 2017 it was all the Harry Potter attractions).
This is just my own observation, but the people who struggle the most on the Boards with wait times at Universal are ones who come from going to WDW often or solely WDW. Because over at WDW they have for years and year prioritized getting way too many attractions under the get ahead of the line product adding attractions from the moment they open combined with a terrible ratio of that with the standby line. This means people who come from WDW are so used to getting 15-20mins or less with it that the idea of not having that is off-putting. I know people who to Universal multiple times in a year often find they wait a minimal wait too with EP but there is a different set of expectations over at Universal (unless they completely change with
Epic which is very possible) and people are at least on the surface more willing to wait for an attraction to get it, Disney on the other hand would have full on riots if their newest attraction didn't have a way to bypass the line even though it's actually not the best for guest experience
overall to have one.
As far as your comment with limiting a number of people in the land there has been a lot of talk about how the design of the portals would allow Universal to limit who can come in and out of it by means of a virtual queue or not. I'm not sure if you've done Universal before but they limited people when they opened Hogsmeade and when they opened Diagon Alley. They would have a return ticket you'd get if the area was at capacity at that time or you could wait in a queue outside the land if you were wanting/willing to. They also limited how many people could come in and out of the wand shops once you were inside the areas. The point being Universal has done crowd limiting in the past, they can do so in the future and Universal hasn't officially said one way or the other (that I'm aware of) how they would handle each portal.
FWIW I was in Japan in October and went to Tokyo Disney Resort, to understand some of the crowdedness is to understand that the people who most visit these parks
do not have an issue with waiting in line they just don't and because of that it does improve your experience when you use their products (for TDR that was 40th anniversary pass that was free and DPA-Disney Premier Access that is paid) as well as if you paid $$$$$$$$$ for their vacation packages that come with DPA passes). It's the opposite in the U.S. in which case people have largely over time been trained to not wait in line, are impatient and thus just naturally expect to get through the lines very quickly. Trust me at TDR when I was in those standby lines eventually I did get frustrated myself but that was after being in line for 60-80+mins with people taking forever because they were snapping a million photos of themselves.
