For you TWF-ing barbs, are you considering any of the new shroud weapons?
For those that have them, are any of the new shroud weapons more DPS than dual Deathnips, or take down non-boss fodder faster than two w/p rapiers?
An off-hand weapon with Earth Grab (for the auto-crits) seems nice, but the 5% proc rate is the same as a weighted 5% warhammer. Although the shroud weapon will have a lot more additional damage from the acid burst.
What are you using or looking to build for your barb?
