Afternoon all you legendary Barbarians of Diablo 3!

I’m just curious if you guys/ girls could give me a bit of advice on my gear and build? I’m running a HOTA Build and I’m just wondering if I’m going in the right direction?
Currently, I can clear through MP7 with ease and can do MP10 with a barb friend (similarly geared) without much trouble.

I just want to get to that next level! I mean, I guess it requires me to get all the incredible off set items, like a Mempo, Ice Climbers, Witching Hour and that... but are those my only options? Is there a way to improve my character without breaking the bank?

Here is my barb: http://eu.battle.net/d3/en/profile/teocyn-2103/hero/7762639

Any help would be awesome!
