I apologize, I was completely under the impression that you did not want to have to work on other crafts in order to repair your gears. I would have thought that the level up button would be a middle ground. We can keep all the crafts yet have an easy sweat free way for everyone to get their crafts or battle jobs up. After all, I'm sure it's much easier for the devs to code an sp reward trigger than to rework all the repair conditions.
