Yeah, I saw that. Now Druids can AoE tank too. It was much needed.
Edit: And Warriors. I'm kind of happy about this, actually. since it means Paladins (or Death Knights) will no longer be required for pulls with large numbers of mobs.
As I said before, Blizzard is moving to a philosophy where no class is required to make a functional group. Warriors, DKs, Druids, and Paladins will each be capable of effectively taking on any tanking role, even though some will still be slightly better than others.
