Prices for minions and beachware/beachware components have shot up significantly due to the lack of farming/access to their specific fishes, Olgoi-Khorkhoi/Gigantshark ect. I consider them useful because you can make a decent profit on them, the problem is that even trying to do so is an absolutely frustrating experience.
The major difference in this comparison is that raid groups can get better and improve their play, where-as fishing is just weather or not RNG decides to screw you. Even if you are fulfilling all the requirements for fishing you still likely won't get the fish in a reasonable amount of time.
