The armor is definitely an improvement. Resistances are still only 200-ish, but that's way better than 140-ish. I can tell there's a difference. I went ahead and took on Butcher with the Wizard. Killed him on the first try with no scary moments. Act 2 will probably be scary though...
Anywho, my poor Barb who is parked at the start of Inferno was the beneficiary of some farming.
Not godly, but not at all bad either. A step in the right direction. The life drop was offset by an amulet I found. That piece isn't worth screenshotting, but it's way better than what it replaced.
Still got a ways to go in gearing up this Barb.
