These new icy fish I can fish up in particular are going for 130g per fish. You can fish up about 12-15 in the three minutes the fishing pool is active before flying off to the next pool. So that's almost 2000g for 3 measly minutes.
I remember back in BFA when I chose to be a Warrior Tailor because of how much embroided Deep Sea bags were going for. They were going for around 800g a piece. The very first thing I did after beating the story was farm the recipe for it, then got it to the highest rank. I made a killing. Unfortunately Shadowlands killed the price on them.
Shadowlands killed the price on a lot of things! I was so disappointed. There was no point in farming anything, crafting anything. Thankfully they seem to have rectified that this time around.
