A few issues with the ocean I have go as follows:
1: the lunar island is more often than not connected to the mainland through a shallow water bridge.
This doesnt make sense from a lore standpoint because the lunar island is not a landmass that was connected to the mainland at any point, it's a chunk of the moon that fell down into the ocean. Other than that, it makes finding the lunar island much more simple than otherwise which in my opinion massively takes away from the experience of actually exploring the ocean and finding the island on your own terms, more it feels like the game's pushing you to ignore the majority of the ocean in favor of travelling down specific paths to the island.
2. theres the damn sea stacks everywhere and they're discouraging me from going into the ocean
Recently, a worldgen update made it so that sea stacks spawn in **MASSIVE** numbers in all of the ocean that isn't the lunar island, mainland, or the bridges connecting them. This makes me deeply not want to explore any of the ocean that isn't leading into another landmass to land on. The way this is looking, the ocean appears to be shaping up to only be a metaphorical road or bridge connecting different landmasses, rather than the ocean being it's own actual biome that you can explore and have fun in. I really don't like that.
