I get what you are saying. If the only variables you are considering are the AH price of materials and the sale cost of the item… then yes, if the mats cost more than the potential sale price of the item, then sell the AH mats.
However… I think what happens on a craft, and whether it makes sense to craft or sell mats, is going to depend a lot on several other factors:
- Where have you spent your KP?
- Is this a one off like a bag or an intermediate material, like a weavercloth bolt?
- What level of profession gear and tool do you have equipped?
- What missive/enchant has been selected for your profession tool?
I can’t speak to Enchanting directly as I haven’t put much time into my enchanters. I do have experience with Tailoring in DL and TWW. I started tailoring on my mage very late. Almost a year after the start of DL, and only in the last couple of months in TWW.
In both cases I have skipped going the craft armor route and have concentrated on the unraveling/weaving side. (Looks like that is a mistake in TWW - lol.)
In DL I figured out how to make gold by mostly crafting Vibrant Wildercloth Bolts in bulk. With crafts of Azureweave/Chronocloth on the weekly cooldown. It was completely dependent on Multicraft procs. If you didn’t have the procs on a craft run you couldn’t cover the mats cost. So it would not make sense.
When you start crafting Vibrant Wildercloth Bolts 10000 at a time, pretty soon the 30% to 40% extra (from Multicraft procs) in a crafting session adds up. Along with the Resource procs along the way, that allow a few more crafts at the end. That is where the profit came from. Not in crafting the original 10k bolts.
I have dabbled in TWW tailoring enough to cover my leveling costs (so far) and net maybe 50k gold. I’m super casual, I’m really doing this just to fill the wheels and be done with it.
My guess is that the same method in DL will work in TWW. Just requires some research to figure out how/which procs will yield the best results.
To do this will likely require multiple tools. I have 3 of the Bismuth scissors for my other tailor. One with a Ingenuity missive and Ingenuity Enchant, and two more with Res/Resource Enchant and one Multicraft/Resource Enchant. (As far as I know there is no Multicraft tool enchant? Yeah just looked at my enchanter. No Multicraft tool enchant.)
Also there are crafting additions like Mirror Powder and the Preserving Embroidery Thread.
Enchanting appears to have Concentration Concentrate as well as the Mirror Powder.
The complexity is part of the lure for the DL and TWW profession iterations. I think it’s an interesting way to go. So far I think TWW has fixed some of the problems with DL crafting, but I haven’t really explored all the ins and outs yet.
