Furnace makes a big difference, vile ward? I just tossed together a raekor barb a few days prior to the comm buff and he has 34% 8cdr vw good roll, found a 10% CDR 3700dps furnace the second day of the buff. He pulls 6bil minimum(talking serious bad map, low mob density, long runs) other maps, including ones extremely high density(a map where you can step out from portal and spawn RG 0-100% and still see the entrance to town on minimap density charging it all in <2 mins can spike him upwards of 10b/hr. all in all he averages 8b hr.
bane of trapped
gogok
pain enhancer
1.6m dmg (pre gogok/rampage, gets up to 3m+ with stacks, higher with wotb)
9.3m toughness
I had him originally at 59% CDR before I realized it was overkill and swapped some items off to my pony sader(8% cdr unity, royal ring) hes still got 51% CDR which is plenty. all 3 gems are level 40. Pain Enhancer works great, though I wish the bot had some sort of smart logic for it, would speed things up even more since it ticks white damage for 18-20m a hit technically I could hit some trash mobs and keep moving while it died as im a screen away but bot insists on sticking around to finish single targets.
