Well, I suppose if you have a lot of money in the game, it's basically the luck that you can practically buy everything despite the people that are selling at ridiculous prices.
Carpentry can easily be cut short by buying certain woods to make other woods.
Weaving requires not much effort if you spam Walter's Part Time Jobs and buy certain materials that are really tedious to get, such as Wools.
Refine is pretty easy if you either get Metallurgy to Rank 5 at the minumum to gather 3 ores at once, or buying all the ores from central Ch1 Dunbarton. Either way, you'd still be either buying certain things, or spending things to rank up skills.
Things such as Tailoring and Blacksmithing are simply a quick buying of most of the materials, or rafting for the Iron ingots or so, and still using money to repair everything anyhow.
Kind of shows how easy it is to rank things as long as you have the money to do so, which is sort of just like the buying Nx for advantages.
It almost sounds like you're frowning upon people putting their in-game gold to use. And for the record, Dracius is from Mari. Your ch1 is our ch4. :p
On-topic: The single-most beneficial skill anyone can rank for production-based skills is Fragmentation. No matter what production life skill you are ranking, Fragmentation will always be good for training it. Always. No matter what. For that reason, Transmutation and Alc Mastery are also good skills to rank, and fragmentation-boosting gear is a decent investment.
