Thanks everyone for your contributions. I have a few more questions if you don't mind.

1. I don't see Manipulation when I look at the current crafting rotations. Is Manipulation worthless now? With 40 durability synths I normally do
  1. Comfort Zone
  2. Inner Quiet
  3. Steady Hands II
  4. Waste Not
  5. Hasty Touch until 20 durability (depends on Goods & Excellent procs)
  6. Manipulation
  7. Steady Hands II
  8. Waste Not
After that I'll buff up with Innovation, Great Strides for Byregot's blessing if I have to.

I am not sure whether this is outdated but seeing as I don't see Manipulation in rotations anymore that would seem to be the case. If it is, what is a better rotation? As reference, my crafting classes are level 51 - 53.

2. Should I ditch Waste Not 1 for 80 durability synths?

3. Is Rumination still used post 50?
