I have several different builds who all use a variety of weapons. 1h weapons, particularly short 1h weapons require a lot more skill than people credit them with.
With 2h and polearms, whiffing isn't much of a problem, and the overall sweet-spot is much larger. To use a short 1h weapon, you must have a mastery over landing the hit in that razor thin margin of a sweet-spot.
I personally believe the vast majority of idiot noobs who cry "OMG 1H SHOULD BE ABLE TO OUT-SPAM 2h!!!!" are simply new players who fail to realize that the "spam" they encounter is a more-skilled player taking advantaged of a whiff with their short 1h sword.
Is it a broken feature? Maybe. I'm not even sure a potential fix to this "problem" is codeable.
