What are underwater sealed chests now:
A sealed chest that you have to grab, swim back up to your ship, drop it off, and then go back in for the rest of the loot or another chest.
Why I consider it bad:
Going back and forth for 1 or 2 sealed chests is bearable, but the more there are, the more it feels like a chore. Additionally, if a shark attacks you while you are holding the chest, you have a VERY high chance to die, unless you juke the shark and/or get to your boat faster than you get eaten.
Yes, you are supposed to clear out the sharks, but in the structures with tens of chests and multiple sealed chests, sharks can respawn and attack you out of nowhere while you are busy looting.
What my idea is:
Make sealed chests be tied to the floor, a cliff, a wall, any surface. Upon the player untying them, the chest floats up to the surface and stays there for you to go up, grab it, get to your ship, drop it off, and after that go for the rest of the loot/untie another sealed.
Why is this better:
This makes the diving feel actually rewarding for doing a sea chart/looting a diving pont, unlike the current system which makes it feel like a chore. Plus, now there is a way to defend yourself against a random shark.
An example of this: Rust.
Shipwrecks and random structures spawn in the ocean surrounding the main island with chests tied to the floor, and as soon as the player unties them, they will float up to the surface, where the player can loot them without fear of drowning or someone sneaking up on their boat while they are under the water.
This concept in Rust makes the underwater loot come very close to one of the best ways to loot scrap(road farming) if you execute it with 2 players, because Rust’s chests are higher in number and despawn much faster to prevent lag.
AO does not have that problem due to the lower amount of chests, so I believe this suggestion will greatly improve diving expirience.

Edit: Multiple people let me know that if you pick up and drop a sealed chest, it teleports to the surface. With this information, my suggestion should be viewed as a visual addon and maybe a small mechanic addon as well to make chests be untied instead of picked up. I beleive there is actually a lot of potential, maybe with tool tiers like we have with shovels and with the sunken sealed chests being like the other suggestion and the better sunken chests beings tied down with harder to untie/cut seawed, but I belive this is too much.
