I have one respect left, I’m currently running a singer Barb which believe it or not is doing rather play in hell… It’s just the bosses who slow me down. I need a build which can help me clear my progress through hell.
Which would you create? A WW or Zerker? I’m currently lvl 76
With items on I can rack up to lvl 30 in skills
If you play soft core ww barb is killong machine. It will be easy to pass hell with it .
If tou are hardcore player than zerk is better choice cause in hc one hand weap and offhand shield with max block is required. Also zerk gameplay use warcries to scare the enemies, and that is life saver big time. Also ww do not allow you to drink potions while spin, so you can die alot easy.
This is my opinion, i am not saying that is best,just i play those 2 builds
just throwin this out there, as it is “tried n true”…
you could always try a “Concentrate” barb.
as a matter of fact, once geared probably, this build CAN farm organs.
admittedly, it’s not so great at killing trash monsters, but it sure is fun seeing elite / champ / boss monster health bars drop in fat chunks.
My favorite would be frenzy (minus taunt synergy) and max ww hybrid. Having a blast with it 
… pure frenzy or ww get repetitive.
My build:
Max mastery, frenzy, double swing,WW,
1pt taunt, find item, berserk,speed,resist,iron skin
Rest in battle orders
Most importanly Have fun 
For boss get urself a reapertoll or lawbringer on merc. That decrepify proc helps ALOT
You can kill bosses easy with singer.
Get Black + SS on swap, put one point in ww. WW the boss until he’s low then swap back.
you might as well just max ww, cause it’s such a waste to just lower boss hp with ww then sing em to death.
defeats the point of havin a singer.
