I will say, as my $0.02/point, that I wish Hyatt had done three things differently:
(1) Commit to a cap (even an approximate one) of the number of nights that can be in the higher categories. A 1:1 ratio of "higher category to lower category" seems fair, or alternatively have a capped average tier. Alternatively, require that at least X% of nights be/remain in the lower categories.
(2) Cram down some share of the hotels that have gone up over the last few years. A lot of the 22% or 37% or whatever in hotel rates has been "covered" by lots of properties sliding up - multiple categories in many cases. I think a lot of animus would go away if Hyatt had said "Yeah, we're knocking about 150-200 hotels down a category as part of this shift."
(3) Start moving category redemptions in smaller amounts on an annual or every-other-year basis (with some downward pressure on hotel categories alongside it). For the most part, this might be 500 or 1000 points at a time - ideally it would roughly track hotel prices and limit category inflation.

The thing is, I can see where there aren't going to be many (if any) hotels where a 3000 point night "makes sense", so I get the need for some re-adjustment in pricing over time.

At the same time, if Miraval and Park Hyatt both evaporated tomorrow I wouldn't even notice and I'd be just as glad if they dumped Mr. and Mrs. Smith. I remember when SLH got brought in and they initiated Cat 8 - my thought at the time, as I recall, was that I'd rather they just not have those hotels...I just don't "get" them.

I won't lie - a shift to a straight revenue earn/revenue burn program wouldn't bother me (as long as there was a decent correlation to the lowest-available member rate and the point value wasn't a total gutting - though I know Southwest has played games on this front as well). What annoys me about Marriott isn't that there's variability or dynamic pricing - it's that the pricing is all over the place with little rhyme or reason. Hyatt's got some similarly bad rates (e.g. NYC hotels that are $120 as a Globalist but would require 23k points to book), but at least the chart is what's doing that.
