Nah, given the less reliant on 'trickle down/scale up' when compared to the initial release the only truly efficient way of doing a craft is leveling DoL then level DoH in order of what you plan to level, for example if you're a goldsmith, it benefits from leatherworker and blacksmith, so you'd level all 3 if you wanted ontop of Miner mainly, otherwise spend gil to make gil.

The way crafting seems to be now is quality has a higher effect on your exp return for an item if it's 2-5 levels above you, so if you're looking at it more for the skill up then profit route, there's no real "efficient" way other than getting as high as possible quality on your synth. If you're looking at it for making a profit as you go, http://www.mozk-tabetai.com/ this site along with seeing what sells well (if it's under your craft) and if its around your level would probably be as efficient as you can get. Crafting changed quite a bit over the year.
