I like this post because it gets to my point about how most people don't understand what they're missing. Maybe it's because so few people experienced A-mode. Or maybe they remember A-mode and just sorta imagine it as they zoom by the Yeti. I dunno. But the bottom line is, there's not a huge uproar about fixing the Yeti so it's not a big priority to Disney.
For me, it's the difference between a "must do E-Ticket" attraction (like Splash, Soarin' or Tower of Terror) and a thrilling secondary attraction like maybe Dinosaur. I'm with Martin - we frequently skip EE now especially if the line is long. But if the Yeti was functioning, we wouldn't miss it.
I think what makes the comparisons so difficult is that EE is such a unique attraction. Trust me, the Yeti swiping at the train IS THE HIGH POINT of the attraction. So while the comparison of the big drop at Splash isn't exactly right (since EE still functions as a ride and Splash without the drop probably wouldn't), it's not totally wrong either.
Maybe it's like doing Space Mountain with the lights on. Space becomes more like an average coaster. Still fun to ride but nowhere near as thrilling.
