Your barb looks as though it should be able to survive mp10, but not kill anything very quickly. Is that what happens, or are you dying a lot as well?
What you've done is bought a number of mediocre pieces, and put together, they aren't quite good enough. The main problems I see are:
- not enough attack speed. With a +0.24 Echoing Fury, you need 34% ias on gear. You have 24% and a +0.21 EF. Never buy an EF with less than +0.24 aps bonus.
- stacking ehp on jewellery. Your rings and ammy are for dps. Vit and ar go on shoulders, chest, head, pants and feet.
What to do about it depends on your budget. To get your ias up I would suggest a decent pair of lacuni prowlers instead of those bracers. That'll give you another slot of ias, plus ms - ideally you want 24% ms, but you only have 12. Then get an EF with as many as you can afford of +0.24 aps, high damage, socket, cd, str.
Once you've done that I expect you'll be able to change Wrath of the Berserker rune to Thrive on Chaos and you'll be able to permawrath and hence do a lot more damage.
After that look at moving ehp off your jewellery and upgrading your other pieces.
Edit: I just realised that with your current 24% ias on gear, you'll need a 9% lacuni and a +0.25 EF in order to hit the 2.5 aps breakpoint. It's doable, it just cuts down your options a bit since your existing ias pieces are all 8%.
