Be careful painting all the opposition with a single brush. I would love to see Fighters get improvements. But the swordsman in me (and yes, I actually train in and teach the subject) can't get on board with "damage on a miss." For me, there is no reason to have damage on a miss. I would, however, be totally okay with "carry-through damage" (where one attack levels 10 guys) or characters who get so strong/skilled with their weapons that they can produce shockwaves of force, or whatever.
Other people may have different objections for different reasons, but that's mine. I have thematic problems with some of high-level D&D, but Fighters who could pull off feats like Beowulf, Cu Chulainn or any one of a number of Greek Demigods is not one of them.
