On a side note, if it takes half the time from revered to exalted, doesn't that make it basically cost 10.5k rep? Making it faster than getting to revered?
Exalted 21k (21/2 post patch) = 10.5k
This seems... odd. And given the fact that each rank has been giving more and more dailies, I feel as though twice the rate is an extreme overkill.
