I'm just going to preface this by saying I don't know how possible and reasonable this idea is because I don't know how servers and worlds work. I think that moving the dueling arenas into a different world would be beneficial for the future of dueling. It would be accessed in the /me menu. Right now, you can only enter the dueling arenas from the great hall in Hogsworth. This means that if you want to duel out of classes, you have to leave wherever you are in the world and firedust to Hogsworth. If the arenas are in a different world, that means you can access it from anywhere, and there would be more people willing to try dueling.
I've talked to others about this, and the only problem they could think of is server costs/performance. If the server costs/performance doesn't suffer that much, I would like this suggestion to be implemented, but I don't know how much that would be affected. Another problem could be the Room of Training because you can fast travel to Hogsworth with that. It could be removed from the arena selector, or a better solution can be thought of. Honestly, removing the Room of Training wouldn't be that bad since it hasn't been used actively for years and the Halls arenas are all FFAs.
Another way this could be done has an NPC in all towns that would teleport you to Halls. It would just track what town you came from and whenever you would leave, it would teleport you back to the same town. This would also have to remove the Room of Training from the arena selector.
