[quote name='AshesofWake']I can't find anything about these being useful, apparently. I know you can compare yourself to your friends to see if you havemore points of what not, but is there a bigger purpose to these? at all?[/QUOTE]
It's to match you up with players of the same level as you. As J Allard explained it, if someone has 2000 points with only 3 games then you can tell they are more hardcore and know a lot about the game compared to someone who has 2000 points with 13 games played. That person doesn't spend much time with a game, thus probably isn't as good.
