Durability management was already pretty trivial in a sense. But, I can see why you're against it, since it does remove the need for repair powder (Providing you can afford the asagos to get one anyway)

Still, as far as donator items are concerned. It seems one of the more "I might need it, but most likely won't" ones. Whereas alchemy/kitchen sets have a great deal more application. Being able to churn out PR-Hi's and food on the fly is a valuable asset, so repairs as well would be pretty nice for BDPers.

Of course, to make it that little less trivial, stick a murai charge on it, like actual smiths.
