I think that's my point, the earning was pretty ok initially. Then it reduced for "the kangaroo route" at about the same time as the EK partnership on the kangaroo route". I agree 100% the cuts for MH was all about the EK partnership, or maybe that should be my opinion.
Moving I and Z in 2022 is just a refinement of the same cough... IMO.
I also note that P has completely disappeared from 1 August 2022. I know the existent is MH first is very questionable, but assuming it's still a thing* given A and F are still in the earning table.
Imagine buying First can getting ZERO.
As for fare classes, my recollection is that the MH website actually gave the fare class before you purchased. Maybe that's changed since they moved to Amadeus. But this was how I got MH awards that I knew would earn on QF, back in the day. Certainly devaluation of QF earning on MH can't have been helped by people earning on MH awards.
*I thought I saw an advertisement for their A380 restarting, or maybe it was an a350 to LHR
