Fishing has too much RNG

[Shadygrove]

.... I tried to fish Red Coral for a GSM who contacted me. First, I went to North Bloodshore for it because the bait people said to catch Red Coral (Herring Ball)

Sinking Minnows, made by goldsmiths, has a far better catch rate for Red Coral.

So I moved to Sapsa Spawning Ground, and the rate of hooking Red Coral was slightly better, as that place has only 5 kinds of fish.

I am eyeing the Isle of Umbral now, but I have to finish more main story quests first. There is a spot there that has Red Coral and only have 4 kinds of fish total.

Reaver Hide has the best bite rate, only 6 other fish, one is a mooched fish, one is double mooched, and both have no commercial value. Its a bit past the Spawning Grounds. Unfortunately the Isle of Umbral is not yet accessible.

Also the sinking minnow will not catch oysters or lobsters, leaving you targeting only anchovies, gobys, and coral.
