Produce has always been available on vendors so that people with bog houses are not at an unfair disadvantage for cooking. Now that there are skills requiring herbs we really need herbs on the vendors as well to even the playing field across housing types. It's really not fair that bog house players have easy access to both herbs and produce, while players with crop houses have to deal with all the nastiness in the community herb gardens or pay inflated auction prices for herbs. Hopefully once we can customize houses we'll have a crop/herb choice and at that point the vendor herbs could be removed.
