I'm feeling a little stuck with my barb. I'm using a survivability variation of the hota/rend builds, it's good enough most of the times, but every once in a while I die pathetically, and I'm not sure how to improve that. so I'm looking for sugestions.

I actually know ONE thing I should improve, I'm missing life steal, but a skorn with life steal is more than I can afford at the moment, and I'm not sure if changing Unforgiving for Bloodlust is a good idea...

I also saw a number of profiles using hota/rend builds with 2 weapons instead of a 2-handed weapon. is that viable? hota causes 325% weapon damage, and rend 700%, in my mind it made sense that I would take the best of these skills using a 2-handed weapon, but now I'm not that sure.
