It depends on the game type. If it's an objective gametype then someone with a low kd can still greatly help their team with good callouts, distractions and assists. Kd does not directly correlate to being someone who wins gunfights (1v1 both shooting at eachother). It can also mean someone who camps in the back of a map with an ads sniper. He might help the team with 1 or 2 kills and 0 deaths but he sure as hell wasn't helping with any objective or flank. Team work is more important then a high kd. Some people with high kds play like pussys and are afraid to get the job done worried if they die their kd will go down. In a game like destiny it's a constant grind and I'd rather complete a game sooner rather then later so sitting back padding your kd makes games take twice as long. I'd rather have a guy go 25 and 28 then a guy go 4 and 0 in a clash game.
