It was literally added in the most offputting manner because it was a joke from the developers. It's taken how long just to balance the classes for PvE? And to spend all that development time to rebalance for PvP would be a ridiculous waste of resources and kill the game because they wouldn't be able to put out any more content, much like all your other pie in the sky ideas of how the game could magically be better if only they had unlimited time and development capital.
Your constant posting of "ideas" doesn't help the forums or this game or the developers to figure out what's worth their time.
