I have to disagree with this. It os pretty foolish to use macros in this crafting system. It is too dependent on changing conditions. You have to build your entire crafting strategy around the flow of Normal->Good->Excellent->Poor. They are random and macros can't adapt to them. If you are macroing things, you might as well be using Quick Synthesis.
In my experience, in order to get the best results you need to build your strategy around making the most of Good and Excellent opportunities. That means planning around using actions such as Steady Hand and extension skills only when on Normal, and making certain to use a Touch action when a Good or Excellent appear. You also need to be certain to avoid using a Touch action on a Poor.
You can eek out a lot of quality by paying attention to the situation. Knowing where you can spare a little energy during one synthesis and when you have to change your approach on another.
I'm a level 23 crafter and I can get HQ items fairly reasonably on 40 Durability items even though I don't yet have access to the really good abilities. You just need to bury your nose in the system and really learn how your skills interact. I for one advise against Great Strides. It burns too much CP for too unreliable of an effect. It is useful if you can land it on a Good, but that is too unreliable of a situation. Otherwise, you can make two Touch actions for that CP cost, and get more quality. Also, moves such as Manipulation and Waste Not are generally much more powerful than Master's Mend, since you can control the timing of their activation more (and thus plan around Goods). Master's Mend 2 is useless for 40 durability, but Waste Not is ideal for it.
Crafting is all about paying attention to the changing situation and maximizing your efficient use of CP and durability. If you make any shortcuts in your creation process you will get inferior results.
