Hello,
during my Team Fortess 2 gameplaey i noticed that gametracker doesn't count points correctly. As I noticed it count only actual kills as points, instead of counting assists/ capture points/ etc. It is very annoying, especially for medick players, wchich do great job as healers and don't get ranking position for that. Is it possible to change this system?

Gametracker counts what the server tells it.
It asks the server for a 'score', and that is what it then displays.
It also is unlikely to be 100% accurate as it only asks approximately every 4 minutes.
