Please consider the archipelago approach to W13 map generation
I think the continents should be much more similar to a Indonesian type of ocean land mass
similar sized continents to W12 but with the dead ocean space littered with tiny islands
much of the ocean between these islands is coral reef, kelp forests and areas that are generally very alive with flora and fauna
these can be new ocean biomes with tons of fish nodes and floaty foragables like new seaweeds, birds, corals, coconuts and more
tiny islands can be sandy or filled with mossy rocks and fun marshy vegetation
I'm sure a couple new little biomes could be whipped up in 2 weeks and a change like this would be very worth the trouble, making ocean boating much less boring and much more rewarding, boating over reefs and shit could still even do damage ticks to your boat but there would be more places to land and more things to see on the journey
