I saw this interesting statement in a forum thread: "the concept of one hit point mooks is such a dissociated mechanic that it completely defeats the purpose of an rpg IMO."
I have a strong dislike of mook rules, but the use of 1 hit point isn't a problem to me. And it's certainly not dissociated from the fictional reality, to me. I chalk this up to the different ideas about "hits". To my way of thinking, one hit equals one kill. Well, a one in six chance of a kill. If anything, it's the damage roll that's dissociated.
