Non-raiding Disc Priest Chest

I'm confused - 4.0 != cataclysm? I thought they were one and the same

Blizzard always releases a patch before an expansion that includes most of the over-arching itemization changes. This often happens several months before the expansion actually comes out. So all of the changes to gear/itemization will happen in that patch which will be 4.0. Then months later Cataclysm will come out and provide new content and such. This happened when Wrath was released as well, though I don't recall at the moment what all changes were in that patch. It is quite likely when paladins began using gear more in line with other tanks instead of spell power, though I can't swear that it was that patch that did it.
