Well the current crafts are not exactly demanding as far as stats go. Thats what really needs to be introduced Crafts that have high stat requirements and require rare but none grindy mats. Having a few special skills that are needed to craft certain recipes with condition requirements to being met to use them. That latter one I would not put on every recipe just a small handle full of difficult challenging ones. There are plenty of ways to avoid rng create a challenge and keep the ease of macro's too avoid hitting a bijillion buttons on stuff that is not extremely hard to craft.
