PS: I think you could have brought this on a way more polite way
I´m not being polite enough?
Either you are an extremely sensitive person or, clearly, we have different views of what it is to be polite. Sorry if i don´t sugarcoat things for you, i just say things as i see them.
Delicatessen aside, i´ll take the time to go trough the works on what i feel doesn´t cut it for playing HC
Frenzy heals 13% life after killing a guy
You plan on killing a HC mob with frenzy alone? Maybe you can, but i highly doubt it.
Besides...Frenzy is the lowest spammable fury gen. Why don´t you try Bash+Golden Rune...10 fury a pop.
Whirldwind regens 1.3% each crit 0.4 seconds for an attack means u attack 2.5 times a second
Leap strike has stun and is thus both escape and start mechanism (could be replaced by healing spear or healing charge)
Lets assume you can "use" WW with this build. 14fps is not something easy to get with your build. To say the least. you wil need 5! frenzy to get 1!!! second of WW... Or 1 Leap Attack.
Leap strike is great.
While ignore pain is active also heal 23% of damage dealt
battle rage makes u deal more damage ( = more heal) makes u crit more ( = more heal) and gives you more fury which means u can spam more abilities and wrath of the berserker length gets increased. Aside from that Wrath of the berserker also grants increased crit ( again more heal) increased attacks (= more crit = more heal again and more damage so more heal) and dodge chance 20% as stated in the quote i think you overlooked this skill.
Ignore pain is 5 seconds.!! It is a "oh crap" button. Nothing more.
Your build lacks a heavy hitter for your more dmg=more heal argument to be valid.
Your damage output is WW and at best...Frenzy. Seems rather lacking.
You will have a hard time spamming WW. Since it´s your main damage source, i really can´t see how that´s gonna work out.
WotB has that nice dmg boost, and the very nice 20% dodge yes... but it still feels like it´s a weak damage output. Maybe i´m wrong.
My build revolves around staying alive and dealing substantial damage. It´s versatile enough to do both (i hope). http://eu.battle.net/d3/en/calculator/barbarian#gadbYZ!cbe!YYabZZ
My biggest criticism to your build... it lacks focus and synergies. And fury generation.
Keep in mind this is all theorycrafting, but i do have the previous Diablo franchise games experience. And i know how hard it is (was) in higher difficulties. Hardcore... well, it´s kinda mandatory that you can withstand A LOT of punishment. And not only through life regen, but by constant
If you really have your mind set on WW and/or WotB... try building your other skills around them.
It´s all a matter of preference in the end. But do keep in mind, that for u to have fun in HC mode... You have to be alive. And you only die once.
Hope i said everything with sugar, spice and everything nice.
