Fixing up my S1 Barb on Eternal... Survivability issues?

Background: Played Double Swing on S1. Destroyed everything, partially due to Barber Heart, of course.

I enjoy the DS playstyle so I’m trying to keep it going. Changes made since then is the addition of Tuskhelm, using Ramaladni’s, and getting closer to 925 gear. Damage isn’t as great as some other builds, but it works. Uber Lilith is doable if the AI is tricked appropriately.

The problem I’m having is that even while exploring the paragon boards, I’m not seeing many ways to increase my resistances beyond the 50s or so, and I feel like I’m using a relatively defensive gear setup with little options for more (disobedience, iron blood, might, etc.) but getting randomly one shot is still very common in the high NMs and I’m not sure if there’s a way to fix it aside from something goofy like Andariel’s or Sellig.

I think I’m mostly jaded by the seasonal powers offering defense through extreme DPS or S2 literally making players invincible. Can other Eternal barbs tell me if this is kind of expected?

What are your life and armor stats?

Oh, that is pretty important.

Unbuffed:
13k Life
8.4k Armor

Buffed:
~16k Life
~13k Armor

I’m unsure if the issue is just taking on too many enemies at once, honestly. Bosses aren’t an issue so I’m presuming it’s some combo of bad NM affixes/mob density/non-maxed resistances. Not sure if there’s even a way to get them higher or if that’s some sort of barb balancing mechanic.

Gotta max your resists. Tri res boots, 1 resist roll on pants or chest, 1 rare paragon with the 5%'s around it, and 2 resist gems in jewelry.

Aim for 9-10k armor before Disobedience, and take damage reduction + armor rolls on your chest and pants.

Ez pz.
