Yes, I discovered Preparatory Touch today and immediate 'dafuq?'d it to success. I could see it getting a nerf to 30 durability loss, myself, or down to 150% efficiency. Hell, they could even put in that clause that Rapid Synthesis III has about "must be above this threshold OR ELSE".

If you have halfway decent stats, this will clobber any 80 durability craft currently with all NQ mats. I thought it was going to be a concern that you could get to 75% HQ with mats, but Delicate Synth and Prep Touch just destroy everything. I should note, you need enough CP/craft for the Reuse to be reliably put in there and the Careful 3 to finish the craft. At worst you'd hit another Careful 3/2 to finish it. The Original Macro just has two Careful Synths at the end without Reuse in, but I put it in there to save mats whenever I could.

Again, you might not have CP for Reuse if your gear is lacking, I threw it in there b/c I can.
