K/D is inherent to teamwork. If I am getting a lot of kills I am therefor helping my team. What OP said is just simple logic. When I play with a friend, and we are the only ones that go positive, and we win, that means the two of us had to compensate a lot. I really don't care that not everyone can always get positive K/Ds, seriously, I don't care. But what OP stated is simply true.
