PoE 3.23 Affliction, 3.24 Necropolis Slayer, 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

Feel like I hit a brick wall with this build, I got it to be pretty tanky and I can even survive t16 whisped maps and tank through some crazy mobs, but my DPS feels lacking. POB Linked below, looking for suggestions on how to take it farther from here. Have about 30-40 Div liquiid for upgrades, but I feel like itll take more than that to pump the damage up. Getting all charges beyond 11 seems prohibitively expensive. Is this just sort of the nature of this build, am I missing something super obvious? Considering re-rolling at this point for something w poison to clear juiced t16s and maybe
