That global average of .8 just means that those players are all under performing. Not surprising considering how many brain dead people play pvp. Logically speaking, a player who finishes with a 1.0 contributes nothing to their team since they're also contributing to the opposite team (in non objective game types). Suffice to say, players who finish with a 1.1+ contribute to their team's win while players who finishe with a .9 and below contribute to their team's loss. No one really looks at the suicide stat and almost everyone is looking solely at KDR. So, if you are at a 1.0, you aren't anything special. Just someone who can barely keep up with their deaths.
