the 2x BSH with +15 agi is way better than the barb blade, i guess it doesn't hurt to have both on hand for different uses. I'm not a big fan of the DM stuff though, the +crit % is good but IMO higher agi and stam is more important.
I ran Baron twice yesterday and got soooo lucky. first run i got Cape of the Black Baron, second run i got Beaststalker Bindings, Carapace Spine Crossbow and 1 Bone Slicing Hatchet. just need one more hatchet and beaststalker gloves and im set for MC.
