So currently I am of the opinion that crafted gear lasts too long. With powder of fort and repair deeds basically being free you can effectively use the same gear forever. I personally have been using the same runics I bought almost three years ago.
With the current system being this way it really hampers the market for crafters. As soon as you farm enough to buy your full set baring being killed by PKs or being lazy you will use that same set forever. As a crafter it doesn’t feel good and isn’t a good gameplay loop to sit there grinding hundreds of thousands of materials, bods and time to reach the pinnacle of crafting to just never sell anything.

Remove the ability to repair gear from the game. By doing this you give people a reason to spend the time becoming a GM crafter as well as stimulating the economy by forcing players to use more then one runic set every 3 years.
Since gear can no longer be repaired we should also increase the base durability of all crafted gear by 3-4 times so that you can get some good use out of the gear but not live in it until the heat death of Earth.
Also revamp Powder of Forts to not only increase the durability of items but also increase their AR amounts on a scaling system. What do I mean by this? Well powder of fort applied to cloth could increase that piece of gears armor by .5x, leather by 1x and plate by 2x.
By making these changes you give people a reason to continue to craft runics. You force players to have to repurchase gear every so often which helps stimulate the economy and allows for crafters/traders to actually be those things. It also gives more reason to use crafted gear as the AR buffs from powders will be instrumental.
