Well 6.1 was considered a content patch apparently, and it added tons of stuff that wasn't considered content. And I dunno, all I am saying is that they never said it was the last raid, they never said it was the last content patch.
Vezara, when was the last time Blizzard made a content patch for WoW that wasn't a raid patch? If we aren't counting pre-expansion patches I think we need to go back to Wrath and ICC build-up. (Might be wrong even there).
