It's a bit of work, but I guess it could make money. Make item yourself without augment slot. Have someone send you mats and hope to score a critical. Give the one without the augment to person. RE the augmented one and sell the augment slot components. It's small cash, but it could work.
I suppose I could see some people doing that, and it certainly IS a valid explanation that I can understand, but it just 'feels' wrong to me. Seeing as how the tier 6 augment slot is really only worth ~60k.....I wouldn't think it would be worth it.
