Fish Usefulness

[Protey]

No item was like that until WoTG though. (Excluding nidhog scales which took 7 years to add a use for.) Everything was for a quest, or used in a recipe, or was useful in it's own right. It wasn't always the best use, since some gear was objectively better than others and some food better than others, but you could potentially use all of it. But then WoTG added a bunch of worthless fish, and then so did Seekers of Adoulin. Even the trash materials added in SoA for other crafts is made into usable items, even if those usable items became worthless when a higher item level came along later. But most of these fish are literally not even in any recipe. Just eat your bait and then npc them for less than the bait cost.

FFXIV did the same thing, but at least you can gut all the fish to get crystals for your other crafts, there.

To counter your claims, these fish existed before WoTG:

Before WoTG came along, the Greedie fish had no uses other than to skillup.
Gurnard has no uses other than skillup.
Tricolored Carp has no uses other than skillup.
Lungfish has no uses other than skillup.
Before adding it to Inside the Belly well after it was added to the game, Yayinbaligi didn't have a use other than skillup.
Gold Carp has no uses other than skillup.
Sazanbaligi has no uses other than skillup.
Crescent Fish has no uses other than skillup.
Before level cap increase and adding it to Inside the Belly well after it was added to the game, Bladefish didn't have a use other than skillup.
Tavnazian Goby has no uses other than skillup.
Before adding it to Inside the Belly well after it was added to the game, Turnabaligi didn't have a use other than skillup.
Before adding it to Inside the Belly well after it was added to the game, Giant Chirai didn't have a use other than skillup.
Before adding it to Inside the Belly well after it was added to the game, Tricorn didn't have a use other than skillup.
