Let us craft from Retainer Inventory

[Kitya]

My analogy is sound. Choosing to craft an item for the sole purpose of making money already has a time management decision making built in. "Do I stop to buy/gather the items I need, then take the time to craft the item and put it on the market for a profit, or do I choose another money making strategy?".
Adding an unnecessary chore like tediously moving items in and out of your retainer does nothing to affect this decision making but simply increases the time needed to craft said item. In the same way than answering 13 CAPTCHAs to be able to sell an item on the market board would do nothing but add time to the decision making of selling something to a player rather than an NPC.

Yeah, but it's something that's already in game which clearly makes it "interesting" and not simply annoying, according to him. He probably gets a ridiculous amount of enjoyment over rush hour traffic, too. :P
