I guess that Feedback is buried in other posts. I wasn't able to quickly find where people have said it. It's probably in the middle of MOT 3* Cafting threads that are still somewhat active. A lot of crafters jus saying "4*, use the same rotation now that you have the new stats"
If you are worried about short changing yourself on Proress, Make sure you save enough CP for Ingenuity II.
Actually, your biggest concern should be geting your WVR MAstery Book II. That is more difficult than the 4* Synths in my opinion. I think I needed 3 PbP and 4 CS II's? Anyway, here's some quotes I did find.
Source: This Forum *****Note****** I haven't qualified this. I use Ingenuity II, and haven't stopped using it. Test before aking this for granted. StouterTaru might have been using Ingenuity I, which may not be useful, but I'm prety sure Ingenuity II is, See Jade's rotation below. (I trust her to the point where I had her craft my Aritsan gear, and she HQ'd 3/3 for me.)

So I've decided to dump Ingenuity for 4 stars. The rotation seems a lot more flexible now.

For the past 3 days I've been busy Assembling my full Artisan Set ( minus body ) and Forager Set. These pieces of Armor require the Master II Books and are 4* Crafts. First order of business is to craft the Artisan Off-hand Tools from Blacksmith / Carpenter and then Penta-meld them ( Control +4 / Craftsmanship + 15 / CP + 3 ) This will help in obtaining the 3x HQ Monstrosities for the Trade-ins. They are 801 Difficulty / 8964 Quality and the best you can start with is 1494/8964 if using an HQ Ingredient. These are the necessary Cross-Class Skills:
Hasty Touch
Steady Hand II
Tricks of the Trade
Comfort Zone
Piece by Piece
Manipulation
Ingenuity II
Byregots Blessing
Careful Synthesis II
Reclaim
Why is Innovation missing? You have to try to set up a "Good" condition Byregot's Blessing in the end to be able to get it > 80% If you get enough "Good" Conditions you need to use a Manipulation for 3 extra Hasty Touches. If I miss more than 1 Hasty Touch I hit Reclaim, a 9-stack of Inner Quiet will rarely get you > 15% Quality unless you get the "Good" You need 3x Piece by Piece which I use at the start and your Ingenuity II infused - Careful Synthesis II has to Yield 81 for the final 3 at the end. Once in awhile I can use a 2nd Master's Mend II if the "Good" conditions are flowing, here is a sample:
Comfort Zone
Inner Quiet
Steady Hand II
Piece by Piece 3x
Hasty Touch 2x
Steady Hand II
Hasty Touch 2x
Comfort Zone
Master's Mend II
Hasty Touch 1x
Steady Hand II
Hasty Touch 2x
Great Strides
Ingenuity II
Byregot's Blessing
Careful Synthesis II 3x
Always have Steady Hand II active when you use Hasty Touch, use Tricks of the Trade on EVERY "Good" Status and if you get 4 that's an extra Manipulation and 8 will get you a 2nd Master's Mend II. Don't be shy in using Reclaim, you only need 3x of each and Fieldcraft III are easy to get from the Bridesmaid / Best Man gear to Desynth.
The 4* Rotation is very similar, but you'll have more Quality especially if you manage to secure HQ Materials... you can get HQ Allagan Silk / Leather / Nuggets to help make the HQ 4* materials like Wootz Ingot. Starting from 0 Quality and trying to get to 5783 is a bit daunting, especially with 586 Difficulty. Though for 4* Crafts you only need 2x Piece by Piece + 4x Careful Synthesis II... you save 15 CP.
Comfort Zone
Inner Quiet
Steady Hand II
Piece by Piece 2x
Hasty Touch 3x
Steady Hand II
Hasty Touch 2x
Comfort Zone
Master's Mend II
Hasty Touch 1x
Steady Hand II
Hasty Touch 1x
Great Strides
Ingenuity II
Byregot's Blessing
Careful Synthesis 4x
Again always have Steady Hand II active when you use Hasty Touch, convert ALL "Good" conditions with Tricks of the Trade and use Manipulation / Master's Mend II with luck. You could add Innovation back in the final Byregot's Sequence and not rely on Reclaim, that's if you have enough HQ Materials. You can theoretically start with 2891 Quality and that's actually easier than making Terminus Putty. I have HQ'ed 14/15 4* Crafts thus far...
