PoE Aegis Aurora, Marauder builds

Hi everybody! So, I have been trying to figure out how to make the Chieftain good. And most of the power of the Chieftain is in how easy it is for him to get defenses. I wanted to see how tanky you could get with a Chieftain, and it turns out that the answer is "absurdly". Here's a pob: I based this build on an existing DD CI Elementalist.

And they add together. 15%

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:

Determination for armor, and Juggernaut to get freeze/root avoidance, endurance charges, extra armor, chaos res, and life regen. Leap slam with faster attacks, accuracy gem, and fortify to move around more easily and pick up fortify. The damage output is not extreme, but it's been enough. The mapping is ok, but not zoomy. But standing stil
