What's funny is that this actually makes a kind of perverse sense -- you're going to deliver more force if you hold a long-hafted weapon with your hands further down the shaft, and there was a feat in D&D -- 'Short Haft' -- that let you switch to threatening adjacent squares as opposed to threatening squares 10' but not being able to attack/threaten adjacent.Where you held a polearm would determine accuracy and damage but because of how fucked up the physics were you could game it so by holding it in the right place it caused someone to explode into bloody gibs if you tapped them with it.
But of course, it's FATAL, so it's going to be as fucked up as Gary Busey on, well, any weekend.
