With all due respect, I think a lot of people at Disney aren't there just to do the rides ESPECIALLY at Epcot. I would argue a lot of people, by design, stop in each world showcase pavillion and eat something, drink, buy something, or just look around.
I was just at Epcot a few weeks ago and its a 2-day park easily imo even when I was using Genie+ and got every ride I wanted done.
I suppose it could get more rides to appeal to the rides-only people but imo its better paired with MK rather than AK and HS
