From what I have read, I'm not too impressed with what I have seen on the new actions. All the ones that overlap with Byregot's Blessing are inferior. I am skeptical of whether it will be necessary to abandon my old methods. The rotation required to make master 3 books is ridiculously powerful and efficient, especially when compared with non-cross class rotations available. Those things have 8900 quality and 800 progress with a severe level penalty.

The unknown is the whistle mechanics. It is hard to tell from the descriptions I've read how powerful they are.
