PoE Fire Trap, Marauder builds

POB:

Inspired by the post about eternal damnation and loreweave I made a POB for RF, turns out it isnt that hard to squeeze in, just takes a slightly OP Chaos res ring. Its basically Pohx RF Jugg but slightly changed. I found it impossible to drop purity of Elements with all the gear constraints, but if I would replace immortal flesh it would probably work. Any cluster jewels experts here? Im not familiar with them and I just put in a small one to kinda cheat a little with the Chaos res Original thread:

No need to use the expensive Elder helm with this build. If the new fracture items are more common(lets hope) then should be much easier to craft a really nice staff. Not sure how it will feel with leap slam instead of shield charge will have to test this out. You can remove the awakened gems and stuff like that if you want or have hard time getting currency. Can craft a better staff later or even use the searing touch staff to hold u over for a long time. p.s No one really ever takes the mastery for "cover enemies in ash when they hit you" not sure if it doesnt work as I read it or jus

Theory crafting a Righteous Fire Juggernaut. Focusing on Endurance Charges, Damage and Survivability, then AoE. Tanky, with big AoE. This build will be in Standard, and beyond what is already in the PoB, has an additional roughly 100ex budget. I'm just trying to make sure I haven't missed anything that isn't obvious to me. I like having at or above 5k life, and would like to keep max res without Endurance Charges if possible. It's my first build I've tried making, so hopefully it isn't too terrible. Thanks for any help or suggestions. POB:
