For craft, often if not always, I have around 80 % of the HQ done and still fails (almost always rarely ever succeeds in any of the crafts be it alchimist, goldsmith, any of them really). Rarely I get a HQ done out of the blue if it doesnt reach 100 %.

I think you just perceives and thus remember fails way too stronger than successes.
I do crafting in a huge volumes (and did gathering in the past) and when you look at final results, even though "i saw so many fails at 80%" or "i failed to get HQ for last 10 nodes and failed 4 times in a row with 95%" - final distribution of rewards on 100-200+ items are quite close to theoretical mean.
