My gut instinct was, "Ugh, why are they nerfing everything so badly? That's ridiculous. Just because it's the end of the expansion doesn't mean they need to make it easy mode for us." Then I actually thought (gasp!) about it for a little bit. Looking at the changes coming in Patch 3.0.2, this was a change they needed to make to let us still raid until Wrath. A lot of encounters probably became impossible to beat as they were with those changes, Sunwell Plateau especially. Sunwell was designed with all of the insanely OP stuff players were doing to win in mind. Stacking Shadow Priests for mana regen, stacking Shaman to chain-cast Heroism/Bloodlust, half the raid going Leatherworking for Drums, yadda yadda.
