Specialization isn't the problem. It is our crafting system and the ability to HQ from NQ in nearly all cases that is the problem. Our rotations are designed, within the constraints of how the developers designed the mechanics of crafting, to not require any RNG. Outside of expert recipes, no one is using Hasty Touch or Rapid Synthesis. Back in ShB, we had a Touch that would double our IQ stacks or reset them to 1, but it was a 50% chance. It wasn't used often, so it was dropped from the game.

With that said, rotations are designed to be usable by specialist and non-specialists alike. Many omnicrafters ignore the +15 CP since if they rely on it for their rotation, it means they need a different rotation for the other 5 non-specialists they have.

If you do expert recipes, all of those abilities are great. It helps bait for a good/excellent (Careful Observation), boost your IQ stacks (Heart and Soul) and a way to line up Great Strides and Innovation if the good appears a turn early (Quick Innovation). Also, on expert recipes with Good Omen, you can pop Great Strides right then followed with Quick Innovation for a huge quality increase.

This iteration of specialist abilities is far better than the Whistle While You Work iteration back in HW. I'm not saying it can't be better, but given how the players utilize crafters, there really isn't a need for specialist abilities beyond expert recipes which are essentially optional anyway.
