I very much like the current mechanism for individualizing weapons, armor, jewelry, and spells. It's one of the things that makes Istaria unique and interesting. Tech kits would pretty much ruin what I like about crafting.

I'm guessing this proposal is to help newer players find teched weapons and gear. Instead of making Istaria more impersonal, please add something to facilitate crafter - player interaction: a bulletin board in taverns, where players can post 'help wanted/help offered' notices. Think a LFG facility, connecting crafters and customers. Make notices expire after a couple weeks or a month if they aren't cancelled. This could also be a method for people to ask for/offer construction help.
