It takes countless deaths to actually break gear from 100% condition, and the only type of person who would actually benefit from this is someone who is constantly doing roulettes without even taking a break to manage their gear and has back-to-back queue times. Even then it would take hours, and the solution is still solved by parking your rear derriere next to a mender before you queue. If you're that hurting for on-the-go repairs, then you should actually invest in the system that already exists instead of making crafters even more irrelevant than they already are.
