Just thought i'd make another suggestion.
Most activities in this game earns you different items that make up your income, but not so much with fishing.
Why not diversify the items you get from fishing so that fishing is not entirely at the mercy of ambergris market price?
A simple tweak could be to increase the droprate of the 1 gold trophies you sometimes get.
But obviously that'd be very low effort, seeing something more elaborate would be nicer.
Also like to see them fix losing the fishing party stacking buff on forced map closure, but there's plenty threads on that.
