I don't even care too much about Quick Synthesis failing. What bothers me is that it's not any faster than just hitting 'careful synthesis' as fast as I can. In fact a lot of the time it feels like it's slower than just hitting careful synthesis. I guess I can't be AFK while doing it, but I don't really need more than a handful of NQ ingredients. Unless someone regularly needs to make 100 Cobalt Ingots for reasons I cannot comprehend, there just isn't any advantage to use quick synthesis.
