Let me see if I can summarize.
You have had wonderful vacations at WDW in the past. You expect (as most of us do) for Disney to provide you with a superior vacation experience. You had a good time this trip, but it wasn't as spectacular as previous visits.
Do I have it in a nutshell?
You also suggested that perhaps the focus, because of the YOAMD promotion, was on giving a few individuals a spectacular experience and the rest of the guests are left getting an average one.
Am I following along correctly? It was difficult to keep up after you hit the hot-button-don't-you-dare-mention-YOAMD topic. As soon as you mention that and suggest anything might be off because of it, you automatically will get the, "You're just mad 'cause you didn't win something and you went with overblown expectations and that's not Mickey's fault so there" stuff.
Personally, I think THAT is getting old. I'll be glad when the whole promotion is over so the whining about the whining can end.
If I've got my story straight, you had a good time but felt you had better ones in the past. It happens. I've been a lot of times over the years. Sometimes the magic is overwhelming. Sometimes I walk away thinking, "Eh... I've had better." It's not the end of the world. (No pun intended... okay, maybe I giggled at the pun...)
As for your enjoyment of Universal, what a wonderful thing to find magic at more than one place! I've enjoyed ALL the parks in Orlando for many years and intend to keep doing so.
Thanks for your report and I'm glad you had a good vacation overall.
