Of all the Seasonal Content that didn't return. Why didn't they give us back fishing?

Give us the normal fishing we had back in Season of the Deep. And let us deposit them into a fish tank opposite Lodi in the Tower for rewards. And then add Distorted fish for when there's a local Distortion so we can see how the Distortions are affecting the wildlife. And make the rewards for fishing be the seasonal weapons that didn't get revised.
