I suggested nets that could be used to fish and as a tool for hunting.
This was more meant to catch a batch of fish though.
I would like to see some rare spawns of all animals, and the addition of of unique animals that have some challenging conditions.
E.g. some fish can only be caught with a fishing rod, which in turn is used in a special potion. Or as boost to existing potions. Or a wolf that only comes out during nighttime.
If you haven’t tried it, give Monster Hunter World a swing.
