That's quite disappointing.. I understand that it was a lot for this quest though and if they would want to get the prayers right, they would probably have to delay the quest release. I think it wasn't a bad idea to try to create an alternative prayerbook instead of just a better prayerbook, but that is just really hard. And I think they should stick a bit closer to ancient curses, if they just wanted to create a better prayerbook. I guess this also means we won't see skilling prayers for a while.
