PoE Duelist, Flicker Strike, Projectile builds

(Broken: Pobb.in: This guy is not incredible. Pretty squishy, DMG not really note worthy but he is my first guy. Judging I build him without guides, I think he turned out ...ok. Learned some do and don'ts from him and thinking about recreating him from ground up to just be more. But some tips to actually streamline him would be appreciated. I think i still want some kind of fire ice hybrid duelist. Main DMG being in Molten Strike, but he needs to be a lot more tanky to really get the projectiles going and not be a complete hit and run
