No you don't. The ones that are a mark of a true timid warrior are those with high K/D with a low K/S and low Kills per Hour along with a high hit %. Those are your pickers and vulchers.
ack-ack
Absolute total BS. Here's my current stats and I am not a vulcher. I don't have a vulch yet this camp and I don't fly timidly or run from fights. I fly in the less populated areas of the map, I do hunt buffs whenever possible and I always fly home to land my kills.

Score Rank
Kills per Death + 1 5.25 103
Kills per Sortie 1.50 258
Kills per Hour of Flight 4.07 1430
Kills Hit Percentage 12.91 82

That's on 42 sorties (15:30 hours).
As to the idea posted, I'd say no. It's too much like the days of AW where those who could spend all day playing were the highest ranked. It would give the few hours a week guys no chance whatsoever of gaining any sort of rank.
