It's a bad understanding of the system. It's not a ladder.
You are rated depending of your performances. There is no fear to have.
A good example of what they get it wrong : I often read people complaining that their rating doesn't change a lot after a victory. But the opposite is true too, but nobody seems to notice it
Once you reach your level, your rating won't change much. You can have a 30% win ratio and still be 1800. (that must be my ratio and rating). Because it's depend of how the system is confident about your level and against who you play.
Now, the problem is that some players are faced to their mediocrity (or simply they think they are way better than they are actually) and can't handle it. But that's a problem they have to talk with a psychoanalyst, not me
But what I should remove is the debug message with the score result after the game, and the rank numbers in the global ranking page.
But the last multi-players games (or even solo games) I've played recently were used to put me in a kind of global ranking on way on another (battlefield 3 has all kind of stats and skill rating, and put me in ranking pages all the time, outside and inside the game, x-com has a world ladder after the solo).
I don't see why it's a problem with FA (it's THE kind of game to do that).
