Instead of durability and repair hammers, we should have a Disarm and Disrobe status/effects that allow an enemy to strip your gear(forcing AP use to re-equip), and Crowbars that act like super-lockpicks(rare, but require no skill to use).
With Crowbars in game, no door should be breakable through damage.
It achieves the same thing durability does: you can break things(gold cost) instead of opening them(skill investment), but it does so without the middleman of gear breaking and requiring repair.
