okay the hunter's call is basically a looong grind of boring fishing, here's some suggestions to make it more interesting.
-fishing with nets: throw a net into the sea and wait after a while, schools of fish will swim into the net, reel it in cook it and sell it.
-(medieval) dive suit, or dive bells with hunting spears dive to the depths of the sea and hunt down some big fish these bulky bois will surely fetch a nice price
-new voyages- start with a riddle revealing the position of a beast's liar, throw rare "bait" (like shark meat, or stormfishes) defeat this beast and claim it's meat and possibly a strange trophy.
-trawler ship- bad at combat but awesome at hunting, with two cooking pans, a table to mend your broken nets, and a more complex rigging for extra speed, and possibly much,much, more. if you end up chased by a foe's ship sail against the wind, with its versatile rigging you can easily sail out of your opponent's reach. it would like this, a sloop but with no cannons, a cooking pan were the cannon barrels are supposed to be, and several small sails. there would be a ladder leading to the stern where the wheel is gonna be, then there would be a latch and another ladder leading downwards into a small cabin with a map on one wall and a door leading to a railing on the back of the stern (like the ones on galleons). then there would a stair (in the cabin) leading downwards below deck, here would a table for mending nets, a couple of harpoons and hunting spears (for fighting sharks,megs and krakens), a diving suit like i said before, and two latches on both sides that could open when you need to bail. yes i know the ship isn't perfect but it's very unique and would have even greater maneuverability than the sloop.
-a hunter's tavern near the sea dog's one- there's plenty of space right so why not the hunters move in too. here you will be able to use your "strange trophies" mentioned earlier to get perks like " your sell ancientscales for 10% more gold, or catch spalshtails 30& more quicker.
who thinks that these ideas are good? i honestly just think that hunter's call is wayyy to grindy even for sea of thieves.
