Oh hell yes to actually rewarding good gameplay decisions.

One problem I see though is that this a major positive-feedback mechanism - do it just a tiny bit too much, and after a few more rebalancing cycles you're either looking at a very easy singleplayer campaign or (whether single or multi) a very difficult game that has a hard time attracting new players while possibly struggling to please a hardcore base that keeps demanding harder stuff.
That said... what's people's thoughts about scores? Those let you have game-spanning consequences without making it possible to screw someone over in a way that makes them unable to complete despite significant improvement over the course of the game.
