Like everyone says, having fun is most important.  I am by no means an excellent stick, would consider myself average.  I am willing to go in where it is hot, knowing death is likely to hit a strat.  Some call it suicide, they are probably right, I call it getting an objective done to better the common good.  You dont really die anyway afterall and it is a game.  
I want to fly to live but realize in the MA there is more fun to be had getting in the thick of stuff and in doing so I usually will die.  Hopefully this happens after getting a few myself.   I fly to live in Squad Ops.  That is a different kind of game.  I havent tried the Combat Theatre much but would think I would fly to live there.  Bottom line, score does not mean anything to me.
