Basically, this is a little bit of musing based off the fact that HP is an abstraction, and that I heard that one of a Fighter's features in one of the Next playtests allowed him to deal damage even if he missed, so...
HP represents not only a person's ability to fight, but also their endurance; in other words, as you are being swung at with swords, you not only get physically injured, but you also lose a little bit of oomph, tiring you out so that your enemy can lay down a final blow.
So, what if any given weapon (or just hand it out via classes) dealt its minimum damage to whoever you are attacking if you missed (not counting stuff like Power Attack; maybe set it to <minimum die roll+Strength Modifier+any enhancement bonus+permanent bonuses from feats>?)? And then, for example, maneuvers could be rewritten to remove saves, and just have their full effects on a hit, and their partial effect on a miss?
Thoughts?
