You may have a severe exp penalty for using automatic mass production in a similar way to how Hasty Hand currently gimps your exp.

This means that if you actually want the items mass production is there, but if you want to level up you may need to grind and do leves. Really we don't know.
That's what I'm really hoping they do. For XP you should definitely have to do the full crafts without mass production. However once you don't need XP anymore there's nothing worse than doing dozens of synths manually because there's no other option lol.
