Tbh, I had crafting macro's. But that doesn't take into account the status of an item. with 40 durability items I use: Inner quiet > Steady hands > Manipulation> Hasty touch spam , And I repeat it every time steady hands are done. Not hard to make a macro of that BUT!... BUT!... I use tricks of the trade every time conditions is good. That might give me a chance to use this combo 4 times on a 40 durability item. On an excellent condition I always use my best touch ability (byregot's blessing once I get that).
In the end, these random conditions improved my crafting by a whole lot just by taking not of it. With a macro you forfeit these conditions of leave it to extreme chance that is is beneficial. Just do it the hard way. Trust me, you end up with better items/more exp per item.
