Good point. Because recognizing that the official Sunder rule is among a select few that stretches the bounds of what's plausible in a fantasy setting and adjusting it accordingly is pretty much equivalent with filling two binders full of house rules.
Why does every thread that poses a simple tweak have to invoke a But where does it end??? sentiment? I'm sure its only a matter of time before someone jumps in and says, "well if you ready a Sundered action you might as well just take dragons out the game too."
