The HQ thing...
I would gladly be ok when I've used NQ mats and in the end will get a 50-95% (adjustable) to get a HQ. In germany we have a saying. It's roughly translated like: "There has no grandmaster fallen from the sky"
Sh*t happens, we all know it. Why on earth do we always have to have success? Sure I can plan ahead, real craftsmen do so too, but sh*t does happen.

I miss times in LotrO crafting (comperable with WoW) with a 30% chance.(? was it even that high?). It was easy to get mats for those crafts that's why I gladly accepted this percentage.
