Due to the many shaman elemental buffs that have happened though out this expansion, I think there is a scaling problem that Blizzard is addressing right now by simply upping the damage as we go though the content. It is also possible that it is like this now, and it is yet another tooltip update.on the negative side, this just makes it even harder for restro to dps. Many other classes get a 10% bonus to their spec's spells, making the difference between damage while inside and outside of the spec not as large.
