Me personally, I want mountable orcas, or some way to travel the ocean at a faster rate, while not risking my boat by flying at mach 5 across the waters. I'd also like to see the world become more challenging/interesting over time, instead of hound waves that can be avoided entirely by just going into the caves, or by placing some houndius shootius behind some statues.
I'd also like to see magic get fleshed out more, maybe be an alternative to the standard melee combat we've had for so long, or just more interesting magic items. It's magic, so pretty much anything is possible.
