PVP area at spawn

I know pvp isn’t the best thing in a server like OR but I have a good alternative that doesn’t turn this server around. (well at least I don’t think it will) Here it is

Maybe we could have a like room we could enter and like the marauder entrance thing it could teleport you to an arena and it would tell you at the entrance before you enter if people are already in a duel and you can watch that duel. And it won’t use durability or make you lose your stuff.
