the odds of soulbound or not won't be on all craftable items, all items will also be salvageable based on their rarity and stats it could give back quite a few mats.
Not a big fan of npcs taking over that but there could potentially be made easier to craft things without always having to be present as the crafter. I.e. having job offers up and the buyer just supplies the mats and requested zing and it gets autocompleted and uses up the cool down of the crafter.
