I've been doing a lot of milling since the prices of herbs, while not 'cheap' have stabilsed pretty quickly. I'm surprised by just how much people are prepared to pay for Inferno Ink (up to 500% above cost)... but it's great for the bank balance.
Some assumptions for the numbers below.
- Inferno Ink is worth 8 times as much as Blackfallow Ink. The exchange rate is 10:1 but I'm being a little conservative, since in WotLK the ratio was at times 1:1, but Inferno Ink is looking to be a lot more useful in Cataclysm than Snowfall Ink was in WotLK.
- Prices for herbs are changing dramatically, so expect that to change from day to day and from server to server.
Sample: 127 mills
Yield of Blackfallow Ink: 1.2
Yield of Inferno Ink: 0.12
Cost of Herb: 2g
Cost of Blackfallow Ink: 4.59
Cost of Inferno Ink: 36.75
Sample: 266 mills
Yield of Blackfallow Ink: 1.23
Yield of Inferno Ink: 0.13
Cost of Herb: 2g
Cost of Blackfallow Ink: 4.35
Cost of Inferno Ink: 34.77
Sample: 36 mills
Yield of Blackfallow Ink: 1.53
Yield of Inferno Ink: 0.26
Cost of Herb: 2.7g
Cost of Blackfallow Ink: 3.71
Cost of Inferno Ink: 29.68
So Twilight Jasmine is currently my herb of choice for milling, since you can pay up to 50% extra over Cinderbloom and Heartblossom to get the same result. I'm not sure if it will pan out (since the sample was only 36 mills) but Twilight Jasmine producing twice as much Inferno Ink is pretty awesome.
I'm really enjoying that I can make a profit from all the products of milling herbs, and it means I can really keep cranking out glyphs for sale at a base price of around 12-15g. Unfortunately Blizzard set the exchange rate of Blackfallow Ink to Ethereal Ink at 10:1, so I have to keep hunting for Outland herbs in order to make many of the (now) most profitable glyphs.
The changes to inscription are fantastic, and I'm looking forward to getting into the darkmoon cards as soon as possible. Today, Twitchie has a trip planned to Stormwind to deliver his Forged Documents.
One last tip: make sure you get your friendly Inscriptionist (or Scribe for you heathens) to craft you a Adventurer's Journal to get a 10% buff to your quest XP. Based on the prices above, you should be able to find them for around 15 - 30g on the AH if there's any kind of scribbling competition on your server.
As prices come down further I'll have a look at milling the other Cataclysm herbs.
