Once again Blizz demonstrates just how completely clueless they can be about their own game. Does anyone imagine that Leap of Faith will ever make it out of beta? At least they limited it to group or raid members, but even at that I see this as nothing but trouble. A quick read of the comments regarding it here will confirm the potential headaches. Between this, and Blizz's outrageous, and completely unprecedented, highjacking of the blood dk dps tree for tanking only, Blizz has proven once again that they are often just flailing around in the dark, with little concern regarding their own traditions or broken promises.
Dammit don't dangle the carrot unless there's a chance that we can get to it: in the case of Leap of Faith, it will never see the light of day in the finalized expansion, not as currently described at least. Unless Blizz is even more incompetent than I sometimes consider them to be.
