Hey, I'm the old roommate Irked mentioned.
As for using Wyld-Shaping Technique to reduce crafting times:
You ARE aware that WST costs Experience Points to use? And not CraftingXP, actual XP you can use to advance your character.
The same goes for Wyld-Called Weapon, except it costs even more experience. And only works for weapon artifacts, so no forging N/A artifacts with it - or indeed any non-weapon artifacts.
Take a look at the original post again.
Spirit-Stoking Elevation (E5, spend wxp on Lore Charms)
Spirit-Stoking Elevation not only says you can use wxp as xp for Lore, Medicine, and Occult charms at a 1:1 exchange rate, it explicitly mentions Wyld-Shaping Technique as an example of one that works. It also explicitly mentions Flowing Mind Prana, the one that lets you spend your XP to buy dots for other people (and later, groups of people, charms, and spells with the upgrades). It also, as written, gives you real xp back.
I am by no means claiming that storytellers shouldn't call shenanigans on this. To my eyes, it is obviously not working as intended. But by my reading of the RAW, this is how it works, and expecting storytellers to adjudicate things like this, especially newer ones who might think "Oh, Solars are supposed to be able to do crazy things, so I guess this is okay?" is just bad design.
As for the money thing, lets take a look at the exact wording.
When finishing your project produces a clear in-game gain for your character, such as a monetary payment, or a new Merit like Allies or Contacts, you gain crafting experience.
Monetary payment. Not "increases your Resource rating". Just "monetary payment." And remember, you are consistently making items of the highest quality, churning them out at the absolute pinnacle of mortal skill, possibly beyond if you throw some excellency use at it. These aren't piddly resources 1 items. You are (or at least, can be) making silk clothing fit for an emperor, dining room furniture that would make any noble jealous, silverware and flatware that belongs at the finest of state dinners, etc. Team up with an Eclipse and you can easily have a constant stream of orders from nobles and city governments (plugging the hole someone mentioned about getting the reward upon
completing the project, rather than later when you sell it, which is an odd bit of phrasing, and hard to tell if intended). On the way to Essence 3, use Flowing Mind Prana with Legendary Scholar's Curriculum and your wxp to train up a small army of the finest of merchants (all with a Defining intimacy toward you and/or your business) and sell your wares across the whole of Creation. Need to diversify? Supreme Celestial Focus with Sublime Transference lets you take the sxp you get from selling furniture and spend it on Craft (Cutlery) and Craft (Tailoring). That and you already have Arete-Shifting Prana, which will let you temporarily use Craft (Weaponsmithing) as Craft (Cutlery) or Craft (Architecture) as Craft (Carpentry) or whatever.
As far as I can tell, there are easy ways around all the objections, except the "Storyteller should call shenanigans" one, which is one I agree with, but also think shouldn't be necessary.
