My beloved OttoVanSquasher is finally in Hell. And he's getting is patootie whalloped. Badly. BADLY. I started this character a long time ago (measured in years, not months) and he's the first char i've brought this far. Therefore, he never had a "build" per se, I was just playing around, learning the game.
This is what he looks like now:
Barbarian lvl 68
Vit 113/ Life 592
Id say he's in trouble, but not dead and buried. Lvl a bit in nm (you want to be low-mid 70's at least before really stabbing at hell) From your stats, i think you clearly need to make a frenzy barb from him. Max out frenzy, add some points into a war cry of your choice (BO is good) and if you got points left, add a few to a frenzy synergy.
What sort of gear does he have?
Looks like you should make a frenzier of him. You will not get the highest damages possible anymore, so focus on crowd control for now. Put a few points in warcry to stun your enemies untill you are satisfied with the stun length, then put some points in BO to increase your life.
Most points are in mace mastery, so look for maces, one fast and one slow with higher damage.
I have a similar problem with a werebear I started a few years ago with some friends. We MP maybe 4 times a year and are in act 2 hell atm, with totally screwed up skills and very bad items, but I can still stay alive pretty well because of shockwave. Only some bosses hurt me a lot.
