Thanks guys.
I was a quite upset over these consecutive results that I hate to accept it as bad streak. When I was leveling all my craft, 80+% usually means HQ in the earlier levels.
Now I am even afraid to complete a synth on 80%. In fact I just failed to achieve HQ on a 92% shield. Just a very unlucky day.
It is very disheartening to go out there and farm for the mats for hours just to come back and fail.
Crafting is fun in this game, so I enjoy despite failing the HQ. But gathering is not.
