There are quite a few misconceptions still floating around here - and I don't think the real devaluation for WP1 is as great as it seems. The real issue is that QF have decided to charge for those sears - that is an impost on everybody (regardless of status, and ignore T-80).
The T-80 unblock (if I understand correctly, and I doubt anyone other than QF knows all the details for sure):
- Happens because part of the algorithm that works out which seats are visible to select includes T-80
- The algorithm also includes Pax status as part of what it does
- It also includes PCV - but that PCV is relative to (and here we are not completely sure) some combination of all the other PCV and/or status pax. Possibly looks at only those that have not selected a seat already, maybe the phase of the moon, and a few other things, including how many unselected seats remain.
The result has been that for the most part, row 4 was made available to most pax at T-80, but not always.
What QF has done is said everyone now needs to pay, if they can see the seat. WP1/CL still get it for free, as does anybody who can wait until T-24 (or earlier if on a connecting flight).
In the current scenario, mostly NB , PS etc. can jump in and select at T-80 for nothing (as can all the WP and SG) - so first in best dressed. Now, all can still do so, but need to pay. If you don't want to pay, then you just gamble and see if you can get in during the check in window.
If anything, this change is most likely to actually advantage (vert slightly) those connecting from other flights, as if everybody is too tight to pay when T-80 opens up (for almost all), they get an earlier crack than those waiting for the check in as the first leg.
