I think the nunchucks may be a bit overpowered. They're probably the toughest weapon to counter, as the window of opportunity to knock the wielder out is much shorter than things like the shovel or baseball bat. Personally, I seek out the nunchucks over any other weapon. Sure you may hit yourself, but that doesn't seem to happen enough to balance their power.
I propose one of two solutions: either increase the frequency of self-induced nunchuck injuries, or have them drain stamina more rapidly.*
Of course, I could be way off base and everyone else may disagree. Thoughts?
*Side question: do the chances of hitting one's self with the nunchucks increase as stamina decreases???
