W.T.F. is a PVE win? And as far as outplaying a team objectively in an objective based wz and winning, where do kills come into play? The only 2 maps where i seen kills matter would be a no cap voidstar or hypergate. And even hypergate has some serious strategy involved besides the kills.
I kinda agree with the football reference above. If you play a wz, you play to win, not numbers farm. If you manage to stop another team from capping a natural node/pylon while holding your own, then you eventually win. If the scoreboard says they had 30+ kills each and your team only had 5-10kills each but there's the big green VICTORY sign at the top, do you think they care that the kills were low?
