I personally do not think melding is the way to go with this. Given how easy melding is and how accessible it is, it doesn't feel like something that deserves rewards - we have tips for that.

Rather, I'd like to see a Request Craft interface, similar to Request Meld, where you can submit your materials, see the progress/quality bars, and watch as the crafter makes your items. I think that by watching the craft and HQ progress, the requester will feel it was a job worth commending for, and by virtue of having more "work" involved, the crafter will also feel deserving of a commendation.
