How exactly does this thing work? I can craft for 50k on my ARM before fatiguing, then on my CPT I craft for 30k SP and I'm fatigued. What the hell? How does this thing work, and why is it so sporadic? Is it tied to the number of items you synth? If it does, it is probably the most ridiculous thing I've seen. If I can get an answer to this, it would be terrific.
