I can swap ~150 Life/sec for another ~3.5k hp, doesnt make any difference though
I'm confused, I can utterly trash act 1, stand toe-to-toe with the butcher for a long period (only having to move for floor fires, the pair are too much combined)...yet act 2 I'm getting gibbed left, right & centre. Trash mobs will 3-4 hit me (and when they're invisible and swarmy...that's irksome).
So, what am I missing? I know my DPS is low, but with stacks of soul harvest it's not bad, I've experimented with trading blood ritual for PtV but again, no noted difference.
Defensive stats. You're good for A1 but for facetanking A2 mobs you need more all res. I'm no WD expert (and you'd be better off asking on that forum, really), but I would want more like 400+ all res. With only ~175 physical res, I'm not surprised trash mobs in A2 are killing you in 3-4 hits. You might also have to/want to swap some skills around to more defensive stuff to help you take down champ/rare packs, like maybe dropping locust swarm for fetish army or something.
As noted above, your defensive stats are way low for act II. I ended up swapping out my mojo for a sweet int/vit/80 allres (yes!) sacred shield that I had found. It knocked my dps down from 20k+ to about 16 or 17k, but this was plenty to kill Belial before enrage. Kulle was a laugher of a fight. Other stats were around 25k life, 600 all res, 4k armor.
