I'm suggesting that EMC adds a feature to let players try to design PvP Arenas. This wouldn't require any coding; just adding a forum section for it. If a player decides they want to try to build their own PvP arena, they can make one in a Single Player world and submit a schematic of it through the forums. The community can vote on it and/or the staff can decide to put it into the PvP area. This will add diversity to the PvP arenas and shouldn't require any coding.
