A few ideas that could be fun.

Since before the game released i had been checking to see if any ideas i had been thinking of were already being implemented, but sadly they were not. Thus i find myself hoping maybe itll become a reality later on if this post catches the dev's eyes.
So the first idea i had was pirate clans (or guilds, fleets, whatever youd wish to call them.) It would essentially work as any other guild, you name it and create a roster. You could custmize your flag and anyone in your clan wouldbbe able to fly your flag. As the clan leader, you would be considered head captain or clan master captain or something, but then you can select others to be your captains and they in turb couls choose their own right hand/second in commands.
Along with this comes idea two; clan vessels. Specifically used in a clan server where you can enter raids against famous deceased pirates of the past, maybe even ficticious ones to aqcuire loot based on their legends. Like little devil, itd be dope to fight him and get a sword that looked like a little devil spitting fire (not actual fire, the blade would just be shaped like a flame.) Or being able to get black beards beard as a cosmetic item would be cool too!
My third idea is one that should be fairly easy; a dying system. My character is blonde and i just want white hair yo, why cant i dye that? Or my clothing, its all in colors i dont care for, but i like the designs so im torn. A dye system would clear this up and give everyone mofe freedom to customize their characters.
Onto the fourth idea, and almost the last. Sea creatures... Why is there no siren? No banshee's? No sea gods? But we have the kraken? Granted the myth of the kraken is based on a very LARGE squid (octopus? I cant recall,) but why not others? Id love to see a crew mate get lured to sea by a siren song and then just hear their character scream as the fog banks that rolled in with the song slowly go with the wind, and all thats left of our team mate is their hat abd something comedic like boxers or something.
5th idea, give us the ability to sail with 6-8 people or have an ally system where we can align ourselves witb a crew. Id like to be able to let another crew know we come in peace by inviting them to ally themselves to our group.
Sixth idea is magic or temp curses. They game is full if what seems to be magicnor mysticism, and two of the chest actually HAVE curses. I think it'd interesting to incorporate magic into the game (but to balance it, the magic is not effective against player ships or players.) Or it could just be curses. Say you do some kind of quest where the goal is to attempt to break the curse of you and hour shipmates. Like maybe youre water bound, so in order to go on land you have to bring a pale of water with you or find water every few moments or you shrivil ip and get sent back to the boat. Or maybe your becomes çursed and it starts floating intk the sky if you dont put enough weight into it, or put down the anchor.
Seventh and final idea i had is more so about an accessory. The xbox controller you released looked dope, but id love to sse one in black with gold buttons.
