Yeah, I think they changed it in MoP and in 6.0.2 but I'm not 100% but all the buffs that used to be granted (Grace/Wrath of Air, Strength of Earth, Flametongue and Windfury) have all been folded in as passive buffs now. Kind of sad, but it doesn't take away the utility that Shaman used to bring. Unfortunately like others have said, there was a trend towards homogeneity between classes and every class can provide at least two or three raid-wide buffs now.
In it's place, you have the Fire totem as your main stay with Searing/Magma/Fire Elemental that you'll want to put down, but the rest are sort of cooldown based things that are situational for PvP and levelling (Earthbind, Grounding, Capacitor). There was a raid one (Stormlash) but I think that'd gone now.
