Well to be fair, usually you see people with high KDs and low WL because they play by themselves. Or hell, maybe they dont care about winning at all (i know i wouldnt if im playing with braindead scrubs on my team all the time.) Whats the point in trying to win if your team isnt going to help out lol?
Theres people who play in parties, or just really like preserving their WL and can care less about KD.
Then theres the exact opposite, where they like their high KD and WL means nothing.
It doesnt matter which one you are, i find it dumb that either one criticises the other, its kind of ironic when you think about it :/
In regards to the whole dashboarding thing, its only for people who want to ruin the game for others. Im glad i play on Ps3, its honestly one of the few perks that people cant do that crap lol.
