Late but lets not forgot patch 4.5. There were specific buffs to the WHM despite the fact it's the end of expansion and usually this never happened before because the next one is around the corner and it will be changed then. (patch 2.5 and patch 3.5) However, they did the enmity changes, the HUGE buff to assize and the buff to PI. There wouldn't of been a need for it unless the situation surrounding the WHM was precarious.
