Rope, yes! I feel like all that useless rope was actively taunting me in the game. Maybe one thing that rope could be used for that would be easy to implement and (somewhat) relevant to how it's used in tabletop, is that you could use it for a temporary buff to jumping? It would be abstracting away any animation, but still.
Also, are these forums absurdly unreliable for anyone else? They keep timing out on me, and trying to quote just gave me multiple errors.
