Replace mob arena with /warp pvp "but there's going to be hackers there" bruh shut up there's hackers everywhere, grow up. This would increase beacon and head prices. Maybe this would also fix the special lag that came with mob arena. There would also be a chance, when you kill someone, you would get their head. This would make up for the missing heads that people got from mob arena. Also I know this will not get implemented even if it has supports because that's how good the devs listen to the players.
