@xAAxAAx I'm well aware of all the bad people. In fact, I consider every player I encounter to be a m*ron until I've been proven otherwise.
This is exactly why I suggested a commend-feature in my previous comment. If you didn't get my point I'll elaborate for you.
Whenever you play with a random teammate that behaves as a normal human being as well as perform adequately and acts polite, you'll press the "commend"-button. This act will increase that players karma, and by doing so also increase that players chances of being paired with another player with a higher karma.
If you're a good person, you'll build up good karma and have a higher chance of being paired with a good mate.
