Put archers back the way they were...it was fine. Fine I tell you!
1-body shot kills are fine if the person is wearing light arming, and the shot is from an xbow. The same is true for 1-body shot kills from a melee weapon, if the person is wearing light armor and gets hit by a Flam or Bardiche or something.
It was hard enough to get kills as an archer before...not its really really really hard. I don't play archer btw, but I have in the past on a STF.
