Fishing really could use some love. Virtually all of the fish that are added to the game exist just as desynth fodder for CUL, and now FSH isn't even allowed to collect an actual fish used in new recipes–those come from white scrips. It's also generally so unreliable to catch a specific fish that the only sensible way to farm fish is through a retainer. I'm making bank with shrimp for now, but I've only ever personally caught one because anything more is a waste of my time. Meanwhile, BTN and MIN are the backbone of virtually every DoH class and are extremely reliable. Even if their items tend to be worth a little less, the reliability is so great that they're easily better gil per hour and because of how timed nodes work it's actually worth my time to go get them.
