PoE m4z1keen builds

This is my current build. And I'm looking for ways to optimize it, I feel it still lacks some damage. Survivability is not the best eighter. I have been thinking on maybe get put in a dendrobate but idk, most "top" builds on poeninja uses lightningcoil, I guess for survivability. Please if someone knows, let me hear what I need to do, what I have been doing wrong, and if there is anything right, lemme know that too so I get to learn abit more. thanks
