I doesn't make any sense to my however that you would not get any experience from crafting toward mastery. Everything else does, why not crafting! The next thing I really don't get is, why even bother having a mastery track (Productive Downtime) that let's you gain more experience from crafting, that you don't get anyways. The whole thing is just weird. Maybe it was a bug and they were to lazy to fix it, and now it was meant to be this way! IDK
