I did a very long generation as swashbuckler, and used a very gimmicky 30-15 build when I was high enough level. I used a masterwork nordic short war sword to overcome my relative slow attack speed; with that weapon I was able to actually double-swing people if I used proper footwork.
Don't forget to spam that nudge, one-hander sans shield has the best nudges in the game. They'll be very useful. Generally, I would bulldog on one opponent at a time and w-key into their face, being careful not to get kicked.
I don't necessarily recommend this playstyle, as it is very reliant on blocking every attack instead of using range and speed to your advantage, and you'll need to have rather good feinting/holding techniques to score hits on a person. I'm just letting you know what worked for me.
