As mentioned in the title, on the Timeless Isle in 5.4 they will be introducing an item named http://ptr.wowhead.com/item=102467 "Censer of Eternal Agony" Sacrifice 90% of maximum health to become an Emissary of Ordos. While transformed, you are hostile to all players, and killing players grants Bloody Coins. Can only be used on the Timeless Isle, and flags the user for PvP. (10 Min Cooldown) - This allows you to attack any flagged Horde or Alliance players that are within the Timeless Isle. Once you successfully kill a player you will be awarded with a Bloody Coin which can be handed in for items based on how many you have. It has some great potential but also possible side effects they haven't thought through. A more detailed video can be found on my channel.
