I run d/d + SB with s/d in bag ready to switch at any time. Does take knowing a dungeon to know when to switch weapons but that comes with experience.
Traits are 0/30/30/0/10 (the last 10 can be spent anywheres.) I like the might/fury/switftness on steal. Some like 10 in deadly arts for Mug.
Love the build. Lots of raw damage with great party support skills/traits. Using beserkers armor/weapons and knights accessory’s since I’m still a bit of a fresh 80
Traits I run are
Practiced Tolerance, Side Strike, Hidden Killer
Shadow’s Embrace, Infusion of Shadow, Shadow’s Rejuvenation
Thrill of the Crime.
