Why do people want crafting to be more tedious than it already is? To fake rarity into the market with even more chance that already enters in at the gathering level?

The casino element is quite present in the over melding and gathering area. If you make it "harder" to make HQ using proper method then you might as well just remove skills all together and we can all just sit around blindly clicking the mouse with our face in the keyboard blowing through stacks of mats until the HQ finally pops.
