No since the game doesn't track KD.
I seriously doubt it will make much difference. People like to win but they like to kill and survive far more. Its happened in countless objective games...no matter how easy or difficult the objective is, there are still people lone wolfing it for the purpose of killing others.
Look at
Red Dead Redemption actually, GREAT example. The slowest way to rank in that game is killing folks (save picking flowers, literally) but what is everyone doing in that game when I enter free roam? Not taking out hideouts, not completely challenges, not of hunting or being a NPC murderer...they are killing each other.
Each kill nets you like 10xp where as if you compelety even the simplest mission you get a minimum of 300-400xp.
Ill say it again and stick by it...people (in general) like surviving and killing more than anything else in a game, its the ultimate means and ends reward system to any PvP game. The ranking that will be done will simply go towards netting rewards that help you kill better, ie, sights and guns and the occasional "clothing" for an ego boost.
On rare occasions and who knows, maybe the enitre Brink community are these folks gathered, you have objectively based and win=onlygoal individuals...but I find these folks to be few and far between in the sea of online gamers.
