Your Demon Hunter no good to farm better gears/DE/gems/ToS for the barb?

One thing about barb is their gears are the most expensive 1. CC Mempo with str roll is the most expensive, Inna pants with STR goes crazy price, EF with str also goes the highest price. I suggest u go for Skorn barb like me first la, coz dual wield barb needs a lot of money for weapon and gem. It is more economic to go for Skorn and at the end you'll be like a bulldozer but the only cons about skorn is you'll need a lot of IAS. 

I dunno but DEX and INT CC mempo is not a popular choice here, I can hardly see any DH, Wizzy, WD and Monk wearing it. Only STR CC mempo is a popular choice, If you get a STR mempo with 5.0% CC it will be topped in just a few minutes. Got the $$ also tak sempat bid.  I played at US server with my friend's ID before I actually start my own.   All my friend who played there say they never seen a single legendary dropped at their lifetime. Not 1 people only but 4 of them. Not sure if they are bluffing but I see them still using blue magic items at PL 20 something.  And from what I see the item price at GAH gone crazy because of existence of RMAH. Now some of them rather start all over at Asia server here after see me playing.

Lol, I never buy any brimstone and surprisingly (well, not really surprise at all) that the qty grows so fast now closing to 500 already.

Replace war cry with rend.
It will save you from rubberbanding. And rend works well with skorn.
Besides, change your belt to IK belt to have additional LS.
You should have adequate LS in your build.

Try upgrading other gears. For a start. do some crafting to replace your bracer/ammy/gloves.
