I personally will cheerfully server hop to find goods at a reasonable price! I make most of my gil selling food, and the prices on my food may drop some, but the hassle of dealing with local MB prices will also drop. If I can't find enough of what I want on Jenova without breaking the bank (or at all in some cases) another server is bound to have it. And I'm personally really hoping that new people coming to Jenova will mean my food has a wider buyer base and therefore sells better. I can't get anyone to buy my Ginger Salad or Imam Byaldi locally for anything.
