If you look around, even very recently there was some discussion as to why "awards" and "achievements", especially those which span multiple servers let alone multiple matches, are a horrible idea. Many games end up with servers whose sole purpose is to increase someone's stats instead of actually playing the game.
Tremstats *can* have a similar effect, but since it's only for a particular server it's not quite as horrible. But SlackerLinux has it dead on, for many it's just a reason to camp or otherwise play a certain way, so as not to ruin one's stats.
