Frozen orbs are greed roll only!!!
Seriously though, this is Blizzard paying attention to us. Maybe someone on the forums put up a nice little post that really made Blizzard consider the change. This just reassures me that Blizz knows what they are doing. Either way I get a big sigh of relief over this change and I hope this is in tune with what Cataclysm has to offer.
Maybe we will even get a moose!
