I'd like to see the inclusion of armour sets that'd focus primarily on making bird hunting, fishing and harvesting more viable methods of getting money for late game players.
As to how armour sets would do this? I'm not quite sure yet but perhaps a feathered set of armour could give you 2x feather drops while wearing it or boost the cash you get from selling feathers by 1.5x, just as a suggestion. Other sets could give similar boosts for fishing and harvesting.
To me, Fantastic Frontier has always stood out for it's balance between fighting and exploring the world to gather items to sell. I feel that to some extent, it's becoming more combat focused though with aspects of the game such as bird hunting being neglected, an update like this could really diversify the ways a mid/late game player can make money without just killing mobs.
