Imo, there are some large holes in that list.
I think you and I both know it's not a comprehensive list. There was a limit to the amount of time I was willing to invest, and I stuck to the highlights.
The list features several timed events that members have to plan around or stumble into: MM, attraction previews, movie previews, etc. But there are plenty of additions in recent years which benefit everyone: shopping discounts, dining discounts, lounges, etc. The post I was responding too suggested that:
1) It's the little things that matter
2) It wouldn't take much effort / money to satisfy everyone
Sadly I don't believe either one of those philosophies rings true. MagicBand sliders and magnets were specifically mentioned. I'm 100% certain that I could go back in the DIS archives to a time when those items were distributed and would find posts complaining "why is DVC wasting money sending me this junk?"
Park tickets are the obvious shortcoming. DVC *SHOULD* come up with some sort of offer for members, APs or otherwise. Even if they have to subsidize the cost. (Years ago I was told that DVC incurred some charge for every discounted AP purchased, but I'm not entirely certain if that is accurate.)
There have been a lot of perk additions over the years, both big and small. Still, the overarching response seems to be "yeah but what have you done for me lately?" I don't think there's anything DVC could reasonably add which would change that mindset.
