I find this thread odd as I've just started leveling Culinarian. My FC wants someone to do it and the prices are stable across the server. Our FC uses them at End-Game across the board and as a perishable item they are always looking for more. From what I've been told they are the only stable prices on the server and as things get rolling there will be more and more demand for high quality food items.

I do agree with the idea that leveling Fishing/Botany is key to producing the goods cheaply. CUL synergizes with FSH very well and I've started producing my own higher level/quality bait. I'm leveling Fishing alongside it right now but it's much easier to level DoH than DoL.
