Okay, for the most part I love rules set out by Pathfinder as well as the incredibly detailed setting of Golorian. I wouldn't play the game otherwise. And I get that sometimes approximating things into a set of rules you're going to get things that aren't really accurate of the real world because otherwise the rules would just end up being way too complex. Nonetheless, I do think that there are rules out there so badly written that they end up having strange implications for the world they are supposed to represent. I'm fairly new the forums so I wouldn't be surprised if this has been done before but hopefully it entertains.
Entry 1, what's implied by the rules of feinting:
Active magical beasts, monstrous humanoids, extreme hunting and possibly even the presence of magic itself has led to animals with keen intuitive senses well beyond the animals of Earth. Pretending to throw a ball then hiding it behind your back will most likely lead your dog to knock you over to retrieve the ball instead of running off in the direction you feigned throwing.
More than this mindless creatures, constructs with high mobility and other such beings have intuition beyond measure. They will not attempt to dodge a feigned blow as they can tell it is no threat, yet be perfectly prepared to side step the next wayward punch that heads their way. How they make this distinction is completely unknown but it probably a ripe field of research for those who are more scientifically inclined.
Being primarily the purview of rogues and entertainers it's quite possible that every martial art on the face of Golorian has shunned feinting as a valid tactic in close single combat and the reality of the the combat manuever amounts to pointing in a direction and shouting, "Hey look over there," as emphatically as possible.
