I'd like to know if SE currently has plans to rework the specialist actions or if they're currently satisfied with how utterly sub-par these things are. Given these were most likely an attempt at removing the omni-crafter requirement for making money at crafting makes it fairly sad to see how reserved they are. It seems like SE was afraid of Specialists being TOO good at crafting.
Satisfaction and Nymeia's Wheel are pretty much the only worthwhile actions at the moment mainly cause Satisfaction is a gimpy tricks of the trade and Wheel can sometimes be an 18 CP Master's Mend 2. Trained hand could have a big boost in potency, upwards of 250-300% given the requirements needed, while Miracle is weak and Innovative Touch is just so laughably bad.
I think the main problem with specialist lies with Whistle While you Work and Heart of the Crafter. Improving these will see to it that all of the others, with the exception of Innovative touch, having a much more reliable and powerful impact on crafting.
Finishing Touches mechanic needs to go, the fact you can have a craft fail because of RNG makes Whistle a risk and it only having a 50% success rate is mind boggling. The mechanic of increasing progress potency in stacks of 3 also would be removed. With that, Whistle would have the effect of Heart of the Crafter rolled permanently into it and the CP cost lowered by a small amount. This thematically goes with a specialist knowing how to really get the most out of their materials and be in a sort of comfort zone in their work.
Heart of the Crafter would then be reworked to extend the current state of the craft, as in normal, good, excellent, or poor, for the next 6 or so steps. Cost and requirements would probably stay the same but this would allow the specialist the ability to actively manipulate their whistle stacks rather than just relying entirely on RNG. Crafting at a high level is all about removing as much RNG from crafting as possible and it's kind of silly that being a specialist only increases the amount of RNG you have to deal with if you decide to make use of these abilities.
By allowing very strong RNG manipulation this would make crafting higher tier gear easy for people that don't have the money or time to level everything to 60. The new heart would let one easily spam precise touch which would quickly cap your Inner Quiet stacks. That gives Byregot's Miracle a place as well as offering reliable ways to get good Nymeia's Wheel activation.
This comes from a fully melded almost all 60s in gathering/crafting player. I'd love to see people able to enjoy crafting without feeling like they need to spend millions of gil and hundreds of hours just to start. Crafting is my favorite part of FFXIV and I'd like to see more people take an interest in it if only for 1 or 2 classes. Making specialist really feel special would go a long way in achieving this goal.
