PoE Witch, Hex, Mapping builds

I thought i was fairly capped for endgame content but I can't do past Wave 20 simul, uber atziri (oneshot by every ability...), ubers, Feared, and die once in a while in juiced t16s. Did a 80% deli but 100% is out of reach. Oneshot every 5 seconds in rank500 tota (lucky I'm finished with all tota challenges for the league). Any advice on where to go from here with 40~ divs? Original plan was Forbidden Rite but MBs are too expensive this league. Could I finish 40/40 with a BV, poison SRS, or similar? Doom is great fun and all but it can't do the content I enjoy d

Setting expectations No, this is not a new meta breaker and it's not supposed to be. I just wanted a hypster unique way to clear the remaining parts of endgame my current build cannot deal with (maven, uber elder, sanctums) I also am trying to somewhat contain its budget, it doesn't need to be a league starter but i also would rather not have to farm 100+ divines before being able to get my final voidstones Build concept Doedre's Scorn scales added chaos damage for each curse on an enemy. We then use Anathema to scale curse limit through power charges. We apply curses with 2 cursed

6 power charges, 6 curses, 99% reduced impending doom curse duration The impending doom rework this league is extremely fun, but most variants of the build are using curse-overwriting with Vixen's Entrapment and Cursed Ground / Spell Cascade for application. Impending doom is supposed to be triggered on curse expiration, but it also works on curse overwrite. This feels... unintended to me so I wanted to make an "ethical" version of the build. Long story short, I use a very specific Cane of Kulemak and the "Window of Opportunity" passive tree wheel to get 99% reduced duration of my Anomalou
