Would depend on how/if Camp followers are implemented.
a Blacksmith on your payroll would determine how fast, and how many weapons and armor can be repaired at once (and maybe up to which percentage, after all an apprentice smith won’t be as good as a master smith and, personally, I feel no item should be repairable to 100% (maybe high 90%, depending on the skill of your blacksmith and to make a difference between new and worn)
That said, wear and tear mechanics have never been done right in a game, so if they do go this route the devs should be extra careful.
