The shit I am doing usually (next to writing into teamchat while I am STILL ALIVE, to coordinate the team a bit and suggest some tactics or pointing to a mistake the other team makes or shit. Yes, really, it's not "everyone for himself" on the field 
) often makes my team win. Which I think makes me a better player than most others. Making kills doesn't change anything. I saw Finn being in the losing team for 10 rounds in a row before the patch. Instead of lolstomping everything he could have written some short commands into teamchat, I bet the team would have followed them (mostly). Of course this would have costed time he could have used for killing people, so his stats would look worse. But he would have won more rounds, I bet.
If chadz would follow your suggestions, Finn would be rewarded for first behaviour (egoistic killing spree, losing the round), and punished for latter (setting up tactics, playing as a team). I think it should be the other way round. And that's the case, at the moment. I hope this will never change, and I am confident it won't.
Heheh, funny you take me as the example of a "Ugh, me smash!"-warrior type who gets a large k/d-ratio, but loses matches and a polar opposite to "the playing as a team"-player
When it was tactics and playing with the team what made me win, get kills and bumb over enemies so our melee could get easy kills.
As for seeing me lose 10 rounds in a row ? Hmm... It's possible. My memory is really rusty, but I do know that 10 round losing streaks weren't that common.
