Aventurine is preparing a new skirmisher school for Darkfall. It's called the Duelist, and as you might surmise, it's heavy on damage capability. The announcement post describes it as "an ultra high mobility melee glass cannon." AV says that the Duelist will bring twitch-play "back into the equation" and will likely "be the role of choice for the experienced PvPers."
The post mentions a few odds-and-ends about the Duelist's skill set, in particular abilities like Flurry, Lacerate, and Pummel. The school also features a cooldown reset that works for both Duelist skills and skills from other schools. The Duelist is due to be released in Darkfall's upcoming content patch.
