^ River gave the Doctor all of her remaining regeneration energy.
In terms of lives there was Melody - Mels - River. River gave up 10 regeneration in "Let's Kill Hitler".
On to Moffat though. I suspect there will be a lot of build up to something epic, but little pay off. Moffat prefers to have character's talk and exposit dialogue rather than show us something grand. TV and film are visual medium. You need to show more and tell less. Seriously how much of "The Name of The Doctor" was just character's standing around talking about the consequences of Trenzalore, or what would happen if someone went inside the Doctor's time stream? The same thing can be said about the Doctor's relationship with River. We are constantly told how much they are in love/will be in love, and yet you never see that grow or materialize.
