The only thing I'll say about this is the HQ% on crafting is most certainly not linear. If I jump on CUL to make buttons in a blanket with 347 craftsmanship and 330 control and use basic touch, I'll accrue X quality per usage and my % increase jumps from say 3 to 15. But subsequent uses of the same ability (and quality) increase that % chance in "chunks," which I've never liked. If other systems in the game do something similar, it's a small wonder people are skeptical of the RNG gods. How do you go from 3% HQ to 15 and then to 45 on the SAME number? You don't, because that wouldn't make sense. In a way, the system does absolutely favor failing you.
