Are the people exeriencing the non-kill kill shots playing on PC? Because I am playing on Xbox and haven't experieced one missed kill cam shot yet. Maybe the worked this out of the patch before it went to consoles.
Nope Im on 360 and Ive had failed killcams myself with archery. Ive even found a new bug post patch with archery perks and the killcam. The final perk for archery gives a chance to paralyze and since the patch it and the killcams both trigger on failed shots. I shot a target missed by hitting a barrel in front of it and it paralyzed and got a killcam at the same time. So I think its just a matter of tweaking both the effects triggers it a bit
