The title is given to players who kills 2000 (or at least, get 2000 death blows of) people on Timeless Isle while using the censer.
When WoD will come live, the isle might trensform into a ghost isle where no one is here, despite it becoming cross server, I doubt many peoples will be there.
So, what do you think will happen to the title ? Will they remove it from the game ? Or will it just stay as it is even though it will be impossible to get it ? Or maybe they will make it so it's obtainable in another way ?
