I pretty much expected the same rates, just philo -> myth, myth -> soldiery. That or keep soldiery in the newer/ harder instances and with the old ones philo -> myth and myth -> myth x2 (or more). I was actually expecting that even more once I saw the 1,500 myth books for upgrading relic.

Interestingly, CM (and probably Praetorium) give a worse reward now than if you did them last week and converted your 100 philosophy to 25 myth following the patch.
