Are you wanting a ranged build, or a melee build? In either case, I would skip the dungeoneering ranks (points in Perception and Agility are enough to boost your trap/secret door finding abilities) and Stealth (reason being that most of the boss monsters have the Detection attrtibute which means stealth and invisibility won't work with them) and put ranks in Archery, Precision Strikes, Precision Shots, Massive Criticals, and Rapid Fire. If you don't plan to go the archer route, skip Archery Rapid Fire and Precision Shots and load up Precision Strikes and Massive Criticals.
You have Flurry, which is great, so I know you have at least 6 in Agility, which is good. I'd add some points in Intelligence and Personality to open up your dialogue choices and enable you eventually to pass some key Trait check later.
