I think that you're missing my points.
1. The smaller, scattered bars are intentional. Disney even said so. Guests complained that they didn't like having all of the bars in a dark area at the back of the ship, so Disney spread them out and made sure that most of them have big windows. Some guests don't like the change, but others do.
2. The walking track isn't that popular. For some guests, it's a must have feature. Most guests never use it as a walking track. The Wish still has a promenade and, for the first time, it actually goes right up to the bow of the ship. It has stairs and doesn't loop around the back, so it isn't a walking track. But for most guests, this is probably an improvement. I used to make a point of walking all the way around once just to see everything, but I never cared about using the promenade to walk a few miles in the morning. I'm much more excited that I can finally stand right at the front of the ship. So, again, some guests don't like the change, but others do.
3. The adult pool itself is probably too small, but it's in a better location. The seating area is actually quite large, though apparently lacking in shade. And, there's only one hot tub instead of two. So, sure, the pool area probably isn't quite right, yet. This might be something that's improved on the Treasure. We saw a similar situation with the Fantasy improving on the adult-only outdoor space compared to the Dream.
4. Disney isn't necessarily catering to guests who already have 100+ cruises. The Wish sails 3/4-night Bahamian cruises and those are the cruises that mostly attract new guests.
Again, some guests will like changes and others won't. That's how it always is. Some people didn't like the Dream, either.
