The big duel is fun with a Swashbuckler/Duelist
I'm running swash/Duelist, currently 6/7 and just got to the duel with Lorne. It was pretty fun. I turned on parry and he only managed to hit me a few times. Meanwhile my riposte and flourishes wore him down. It felt like the Oberyn/Mountain fight in GoT but with a different ending.
This has been a pretty fun class so far. I usually like having some magic but there are enough tactics to give some variety.
