Disagree.
If you view AnySeat as a replacement system then yes, it's piss poor. But because it's simply a second layer to grant additional award booking options for those that are happy to spend 50% extra points to get the seat they really want, then it's fine.
The exorbitant rate you mentioned are for seats that QF clearly intend on selling for dollars instead of offering up for points. One could argue "why put them up for award at 1.7m points at all then?!?!" which is a fair comment, but I guess QF see it as an opportunity to remove some points out of the system.
All I'm saying is...those million point seats should simply be ignored as they are not a true reflection of the AnySeat system in my opinion. Having another look today, there are plenty of award seats for similar or only slightly more points cost through AnySeat verses Classic.
