So I'm currently in Act 2 Inferno, in Zoltun Kulle's archives and constantly dying to the snake monsters (the ones with spears) and the fire mage constructs that throw mini-desecrators all over the place. I didn't really have much of an issue leading up to this, but I'm finding my progress has become much slower ever since I reached the Desolate Sands. Here's my Barbarian.

A couple notes going into this:

• I'm playing through using self-found items, so try to steer clear of AH-centered advice. I realize most of my items could be upgraded for pennies, but that's just not how I want to play.
• I've tried switching to a 2h weapon, and I've tried sword-and-board. I can honestly say that, while they might be better, I don't have fun playing those styles.
• I tried other Barb builds, but I really love the skills I'm using now. You may notice a distinct lack of variety (in fact, I haven't had to use Elective Mode for my Barb), so I'm always open to build advice, but I love to facetank things and watch them explode.

Thanks in advance. =)
