It really doesn't. My friend and I were 2v3 in trials for the whole game (friend lagged out before match start) and both have negative kill death ratios mind you, the other team locked and loaded with Conspiracy Theories and pulse rifles and went flawless in Y2, and we simply went in, won 5-0, and got out. [spoiler]Tl;dr, I 5-0'd enemy team with negative kdr and having only one teammate [/spoiler]
