Feedback on my Infernal Blowzerker

So, I sat down wanting to play a zerker this league and have played around with, and settled upon Infernal Blow CoC Dark Pact. I'm having fun with it, but think I may drop Pride, swap over to Blood Magic + Mortal Conviction and just run Herald of Ash.

I wanted to build around Breath of the Council and Chernobog's Pillar and feel like this skill loadout capitalizes well enough on those two items. I feel like I've gotten to the point of a level 74 character that has veered too far into elemental damage territory now, though. I had picked up various mace nodes to enhance attack damage from Breath of the Council, but with Infernal Blow and Chernobog's Pillar both converting phys to fire, would running just a Fire Penetration support be enough? Maybe change to Ground Slam or anything else I can use with maces and just keep Chernobog's for the added survivability the on-hit Enfeeble provides? Vaal Impurity of Fire comes to mind as well for anything that feels too tanky.

Here is my passive tree:

I'm sitting at 30% or so crit chance, 95% accuracy and plan on focusing on max life from here on out. I feel like I could swap out Chernobog's for whatever and swap back to Heavy Strike, Ground Slam, etc instead and go back on track for physical damage, maybe rerolling to Chieftain/Inquisitor/Elementalist and pursuing an Infernal Blow build.

Any feedback appreciated. Is my passive tree bad and should I feel bad? Was my idea feasible until I threw Berserker in the mix? Thanks in advance!
