It may be just me, but i've always wanted the ocean to have more purpose in graal. I had alot of excitment with the release of yorktown, and it made exploration more interesting, but nothing new really happend just some cool islands. The implemation of fishing would definetly help, but I am talking about other things.
Content could include boats, cannoes, anything you can use to traverse water in a unique type of way.
Or; a quest in which you talk to some old EX-pyrat or some treasure hunter and he talks about some legendary treasure that was buried out on these deserted islands. They are in the sea south of yorktown and you need to use his 'ole washed up raft to travesrse into the uncharted waters. If you dont use his raft or a boat (mabye purchaseable in a shop) sharks should randomly appear and attack you.
If you die anywhere on the uncharted islands or water you respawn back at yorktown beaches, being washed up on the shore.
Id say every week each graalians "treasure spots" are randomized and respawned on many small deserted islands out in the uncharted waters. You would be able to go on a treasure hunt and dig around the beaches for treasure. (id say about 5 treasure chests a week, should have alot of ground to cover in order to find them, and treasure chests could have a prize ratio of :
70% 500 gralats.
10% Jewel furniture. (from common to rarest: emerald, ruby, saphire, diamond) could be showed off like bugs.
5% 1000 gralats.
5% Admin/Event hat (could choose different hat sets every week)
5% Old Jenkins skeleton (like a boss baddy? He's rare to find and has ridiculous health like 20.0, mabye range attack too, if you manage to kill him (remember death means respawning on beach), he drops back to bones that drop on the ground. Pick them up and they go in your inventory. You can then use the bones somewhere else and bury him again. Next person to dig there gets an old jenkins attacking them again, or the bones could be traded in for cash oh lets say 250.)
Random but its what I would find fun and make treasure hunting more cool
