Ok, well it does work, and its just info.
Go to the merchant in tradeskill instance. start vendor mode as usual. Hug
the wall into the crafting area all the way to the crafting section. From
there, you can move down the wall to at least the second set of
workstations, and you can use both the jewelery and alchemy stations while
accessing the vendor. Set up shop, set it up to buy anything you need in
whatever quantity, clear out your inventory of everythign but sellable
materials.
Right now it will work with tier 2 stuff from the vendor, as you can buy the
subingredients off merchant.
Now you set the macro up as follows.
Buy 20 candles/coal (however you would do it this is an example)
Buy 20 resins/washes/whatever main ingredient calls for (mine would be
lead/tin whatever is on the merchant)
Buy 20 water / whatever the other component is.
Scroll that window back up to top (so window resets for next round of
buying).
Do the round of crafting
Sell EVERYTHING in inventory back.
End macro.
Rinse and repeat.
The buying while crafting part is the basis of what im telling you though, i
craft for hours without moving just restocking as i need it.
