I'm in favor of this. I used to manually synth everything to ensure the 100% success rates, but it took so long I gave up, and now I allow for several fails when I calculate my costs to make said item. Very frustrating, they should make it so you have to be at least 11 levels above the recipe level to get the 100% success quick synth, because I'm sure we don't want people quick synthing anything 40+ at a 100% rate.
