Interesting.

I'm going to take a "wait and see" attitude for rotations. There are far too many variables, including the new skills and quality/progress requirements to guess what rotations we'll use.

The PBP change is interesting. 1000 is quite small, I can see Observe/Focused overtaking it easily. I've mentioned before that the existence of PBP devalues Craftmanship considerably, I only just meld enough to scrape the 4 star requirement for my rotations and could do them with far, far less if I was allowed.
The Adjusted Control cap is interesting too. I can see it being tedious at endgame melding if we get very specific builds, like X amount of Control caps exactly at X amount of IQ stacks. Also Brygot's Miracle could become very strong, letting you build to 11 then Miracle+Blessing.

We'll see, looking forward to working it out.
