I know that I am not exactly the best archer around, I also know that at 130 my bow still shoots as unprecisely and randomly as a 19th century machinegun - but I usually know when I miss or when I hit, esp. at close range.
Recently I had several incidents that I can not explain - would be interested if other archers experience the same.
Guy stands like 10 meters away, perfectly still (e.g. raising a ladder in siege), I shoot him, see the arrow move straight through his heart or even his head - nothing. Shoot another guy next to him (that even may be moving and harder to hit) - *fump* - Hit. Shoot the first guy again, perfect hit - *sweeeesh* - nothing.
When a target is moving, I can blame it on high ping and server lags, if the animation shows my arrow or melee weapon going through someone without effect. But those incidents were happening while ping was normal, server not too laggy, and the target was static.
Guys weren't using heavy armor either, most of them even cloth / black robes, so no bouncing.
WTF?
