I think you ought to create an alliance of PlaneShift experts who are NOT involved in the actual design and programming of the game. This game has been up for how long? And how many experts on the game do you think there are by now? People who weally live it.
Anyway: Send them the database of dishes, and let them together tell you what a dish will do. You will review their answers, and you will see that they know what they're talking about. I am not an 'expert' on the game myself, but to me it seems right. You have a giant recourse of knowledge you didn't even knew you'd given, there.
