I think before making oceans larger some issues shall be looked up, and mostly - about the current credo system.
Credos like Nomad and Herder were developed for a single-continent world and now include getting on a different continent. I'd like to see how you move your domestic cow across the sea with current mechanics.
Maybe we also need first couple new credos: Sailor and Captain.
Sailor might allow you to repair a boat or knarr while being a passenger of it, could reduce it's "weight" while jumping through vortexes and reduce damage in deep ocean. It can also add speed of single-crewed ships like dugouts, rafts, coracles, and maybe even rowboats.
Captain could be all about driving Knarrs. Giving them speed, resilence, maybe couple other useful perks.
As far as I understand, the current world is more of a "test" of how oceans will work.
Besides, there probably should be added more content about the deep ocean itself before making it just larger?
