ur gear is way too op, prolly costs like 20b pre patch, 100b 6 months ago
i have a budget barb that i made with 200m ~200k dmg ~500k toughness a few months back
i got some pretty sweet cold dmg bracers from 2.0 and went with this build
http://us.battle.net/d3/en/calculator/barbarian#WeVTjP!SZY!YcaZYbi farm torment 3 very easily with no deaths and prolly like ~10 seconds per elite pack
i pop earthquake and call of ancients at the start of the pack, call of ancients do surprisingly well for fury regen that i can spam seismic slam pretty well, i didnt go with hota since the cold dmg hota is weak shit and seismic slam aoe is super helpful
wrath of beserker just serves as back up really, using it with frenzy to dps down a single champ and can clear an entire mob when used with seissmic slam, frenzy smite by itself to almost perma stun enemies
i do have pre 2.0 ik belt with life steal %, im not sure if blizz intended for that to stay, since i thought blizz wanted to get rid of life steal %, but so far it still works and is a life saver
i also have life steal % on my dh from a calamity pre 2.0
