I'm usually against item durability as a rule, but it was handled well enough in DOS1 that it wasn't really a nuisance. I always have a character that has some of the repair skill, repair hammers are easy to find, it doesn't decay rapidly unless you bash your weapon against furniture or run around in environmental hazards, & you can do it during combat for minimal AP, so it was fairly balanced & served a purpose. I don't think anything much needs to be done w/ that system.
