It's not purely about winning for me, as I never play with a fireteam, and the matchmaking pairs me with teammates which are far worse, expecting me to carry them. I regularly have matches with a >2 KD and topping the leaderboard , while the 3rd place of my team already has a 0.7 KD. I have around 70 "on the bright side medals". It's more about performing in the best possible way, to the best of my ability. And with supers/heavy being around constantly, I cannot enjoy this game in terms of gunplay, as there simply isn't any meaningful amount of it in mayhem.
