Hmm...I don't find that a relevant comparison. I just don't think it's fair to avoid the fact that an arrow to the head is lethal...You're talking about reprogramming and mentioning stuff that belongs in a movie... That's a more solid argument, I'll accept that. IMHO if an arrow hits in the head, the guard should drop dead, no matter alert level, but as you said, the alertness will change behaviour in "dodging" and the only feasable way to simulate uncertainty and stress in firing towards an charging enemy may be to alter damage against alerted guards. But anyway, I'll think it's enough to add the restrictions in the style of objectives... And as I mentioned, I rarely use the broadheads or sword so the change won't affect me
