If it's not difficult to add certain edible plants/trees to the spawning system for crafting herbs such as raspberry bushes, cherry trees, turnips, potatoes and other similar items I think this would be beneficial to role play and give certain races the option to eat a cherry they didn't find on a dead body, or happen to run across for sale at murnu's shop. The concept that a persona could live off the land entirely (not just limited to eating animals as you can now) is something that more than a handful of players might enjoy.
