wow, you seem to have a very similar setup to mine but I have way higher stats, it looks like you might not be stacking enough crit hit damage, it might benefit to switch to 2 one handed weapons (or even just 1 one handed with a shield with good defence stats), personally I have the ancient bone saber of zumakis ( I think I spelled it wrong lol) with a radiant star emerald and echoing fury in my offhand and it kicks my damage up wayyyy high, you also might have to invest in finding gear more geared towards returning health oh hit/kill along with skills that do the same like rend with blood lust or the bloodthirst passive giving 3% of damage back to health, instead of warcry try using overpower with killing spree to increase your crit hits as it works well with battle rage with into the fray, I never found animosity or boon of bul-kathos to be useful to this type of build, try using 2 different ones that help you stay alive longer instead of your fury because with your skills your fury is going to regen at a crazy rate anyways and the wrath of the berserker will stay up as long as your using battle rage (and rend, since I use that a) a lot, personally I use bloodthirst and ruthless in place of the 2 you have, and im able to solo master V (or mp10 depending on if your on pc or not) hope this helped out a little
Get rid of that TERRIBLE weapon !
Alternative for 2handers: Skorn (high str, high CD, socket, lifesteal?)
Your overall CD is very low.
