Repairing accessories (Post patch 1.19)
Plan A: Stop loss of durability of accessories.
Plan B: Allow NPCs to repair accessories.
I say why not do both?

Stop durability loss 1st (easy fix).

Then later, add the "Charges" to accessories and allow NPC's to do a partial "Recharge" (maybe even just 1 recharge) but require a crafter to fully recharge accessories. (hard fix)

Give the recharge ability to Arcanist and Culinarian, they need some love.
(Culinarian would give new meaning to "Meat-Shield")
