Was thinking the same thing
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?
Friendly 3k
Honored 6k
Revered 12k
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.
