If those things (minus Vaal RF) are already being considered then it's likely just a matter of preference and expectation.

Should I go flammability + blasphemy. So if it's just the beefy enemies that are bugging you, that'll really help. Looking for opinions here on which of the two options is better. The third curse is coming from Witchfire Brew, as Author not sure how this interacts when you have two blasphemy curses up I went with the +1 curse node. Vaal RF is a HUGE boss killer and time saver. NO.5 PoE 3.2 Occultist Build Sanzais Low Life RF/SR Dual(Tri)-Curse Occultist. We don't always have max Inspiration charges because Enduring Cry has such a long cooldown and as a result only gives us a 2-second timeframe to hit Enduring Cry again. We do need to get hit for all the CwDT perks (like lowering enemy resists, EO, and EE) to take effect which is huge for damage.

So if you activate Witchfire brew before the 'of Warding' flask, the mobs will still get cursed. However the curse aura will activate and the effect will persist even if you gain curse immunity AFTER activating witchfire. The other suggestions would help (and they are good suggestions too) but they aren't going to substantially increase your damage. Witchfire Brew's Despair aura doesn't activate while curse immune (like of warding flask). You've gone with damage where you can in you 6-link and nothing conflicts with EO or EE.
