Yeah, the F+R loss is just something that N6G4 can’t recover from. I gave it an honest attempt this season on HC - I stumbled upon a bunch of perfect primal Nats pieces and gave it a few rifts. Did not impress.
I think N6G4 might be perfect for one thing in S21 - more safely fishing for a 150 solo clear on HC heavily utilizing the season theme. Toss in an elusive ring rather than the CoE and you should be one tanky boi. But I’m sure a zDH build would work about as fine, and would pretty easily be significantly more tanky as well. I thought about giving this one a go, but that fishing looks miserable.
As for S22, if I did DH on HC again I’d absolutely utilize Iria’s spec. Tried it out last night and it is maybe the easiest variant of a build ever constructed in this game. Having constant max discipline and multiple seconds of vengeance & fan cooldown overlap puts GoD into the monkey with typewriters can clear 130s territory.
Meanwhile F+R is the crux of the problem with S22 for N6G4 yet again - everything we’re switching out here are set items, so there’s no real boon from the 4th cube slot that GoD6 also wouldn’t benefit from
