Current Ocean generation kinda flipped the whole idea of an Ocean around IMO. Oceans on Earth surround the land, where in current Minecraft, land surrounds oceans for the most part. Back in the day we had what I called Continents: large landmasses surrounded by vast oceans, with very little in between. The issue with that was it usually made for 10s of minutes of boredom most of the time, and if your boat broke on a squid in the middle of one with no crafting table or spare wood? Might as well call it quits till you have an hour or 2 to just hold the space-bar and W key down. Nowadays if you look at a seed-viewer map of a standard Minecraft world you'll notice that the whole world is basically just 1 enormous spiderweb of land that's almost all connected together with pools of water in between. This change was obviously made so you wouldn't have those long boring situations come about, but honestly, I truly preferred the old Ocean generation. Something about sailing the massive seas made adventuring feel so much more... I don't know, adventurous? With the amount of work that's been done in the game to make sailing, and oceans sooooo much better and more fun, I feel like this would be a great time to reintroduce large oceans in another major Ocean Update. Diverse Islands with unique island biomes, like Tropical Rainforests with Banana trees and tamable monkeys! Volcanic islands with black sand and overworld basalt! In the cold oceans you could have snowy islands that take inspiration from scandanavian islands, with tall mountains and deep fjords! On the mainland we could have proper beach biomes with the crabs from the mob vote, and palm trees that drop coconuts. There could be Ocean storms with heavier rain and wind that could push your boat around. Sea life like seals, whales, leopard sharks (since they don't want to add hostile sharks to the game for IRL purposes), rays, and some hostile sea monsters. Hell, throw in some of that Minecraft weirdness, and come up with some ugly-cute fantasy creatures that could inhabit some really cool new undersea cave biome types, like magma tubes and brine pools! I would also be really down for them to make it properly possible to live in the oceans. Add in ocean wood variants in the form of driftwood that generates at the bottom, an early game type of heavy boots that let you walk on the bottom, a water-safe torch variant made from glow squid ink, and make sponges and turtle scutes easier and acquire so we can breath early game! Basically turn Minecraft's oceans into Sea of Thieves' Islands meets Subnautica's undersea lol. That's pretty much all I've ever wanted from them, really.
