While I agree the failure rate for "actual" recipes is fair, the failure rate for "trivial" recipes is ridiculous and unnecessary.
Quick Synthesis exists precicely so that you do not have to repeat a task you already proved you can perform, over and over again.

It should be completely impossible to fail quick synthesis on a recipe you can guarantee success in less than 4 steps.

Worth noting:
- It is considerably vastly less efficient (XP, HQ rate, etc) than synthesizing yourself.
- For most low level materials (which you can get 100% progress in 1 step) synthesizing yourself is faster than quick synthesis.
