Lets talk about Wrath and the new profession Inscription. Well here you can see that it requires a ton of herbs. With insrciption you have to mill your herbs which is the same thing as prospecting for mining. So a good idea would be to buy any cheap herbs and or farm some for yourself and wait until launch. You should do this because everyone wants to do the brand new profession and have all the cool glyphs and such. This will cause inflation which you probably know.. I figure farming the higher lvl herbs 40-60 will net you more cash since they are more rare.
You could also do this if you plan to lvl inscription as well.

To those of you wondering I did just start herbalism.
