please, excuse me, lemme share my knowledge for you guys

i was a skorn 5ik-set user, and i have a lot of knowledge about two builds for a skorn (2handed) barb!
with skorn and the whole ik set, you can build a strong toon with very low budget, since good skorns dont worth too much gold compared to EF/Mace combos, and the rest of the gear follows the same price logic.
ok, lemme explain my gearset, piece by piece (stats ordered by importance):
- helm: ik with 6% crit/6% melee reduction/armor/170+st
please CARE about that melee reduction mod, its SO SO SO underrated, and makes you surviability much higher. as you will see below, few parts will have it, to burst your EHP (effective health pool - see d3rawr calculator for more info). try to get perfect crit too, and armor (gg EHP boost as well).
- armor: ik with melee reduction/800+ armor
these are the most expansive ik part, so dont mind atm about st/vit, just get with 800+ armor AND melee reduction and you're good.
- belt: ik with 3% LL/reduce rend 5 fury/13 fury/armor/170+st
the perfect belt for a skorn user, since rend is ALWAYS USED (explained later).
- gloves: ik with 10% crit/6% melee reduction/armor/170+st
perfect crit and perfect melee reduction is a must, same as helm.
- boots: ik with armor/95+vt/95+st
easy item to buy.
so far, you have a shitload of EHP (close to 20% melee dmg reduction, 3000+ armor and 280+ AR) and the full ik set bonus, witch makes you rage endless, even at mp0, regardless about wat build are you running (gotta explain it later).
lets proceed with the rest of the gear:
- bracer: lacuni with melee reduction/armor/9ASI
if possible, add another usefull mod (like pickup radius) - you MUST use lacuni to reach 24% moviment speed (the limit for all characters in d3) - and get with 9ASI, more easy to resell ;P
- shoulder: vile ward with 200+st/50+vit
a rare shoulder with 550+ armor and same mods works too, and looks more sexier imo, like doom(61) or archon(63) one - just like diablo2, character appearance matters! if possible, add pickup radius, if you didnt got it into the bracers.
- pants: 70+allres/armor/2sok/st and vit (250+ for both stats, like 150vit/100st, 200vit 50st, your choice)
at this point, you will shout 'dude, why not inna's?'
i hate innas. its ugly (remember: sexiness increase your dps! :D)
nah, to be honest, i prefer a rare one, even the depth diggers one works very well here
again, try to get doom(61) or archon (63)
but... if you really wanna go for inna's, you can swap the lacuni bracer and get another bracer of you choice, since you dont need more then 24% MS.
- weapon: skorn
at least, try to get a 1300+ with 190cd (no less then 190 for cd, since it boost as fuck your dps), 300+st.
if you get vitality @ skorn, it will save your pocket to avoid getting any vitality from the rest of the gear, especially into the rings/ammy/future upgrades, since there's no need to get your life beyond 45/50k ish life for highers mp (including mp10)
please note that you can lower the st to get more dps, and lower the dps to get more st, but remember to test the dps ingame (buy a shitty skorn, enter game, remove any sockets, goto AH, link @ some chat the skorns you want to make comparison, return to game, buff yourself and click-check the skorns)
i never tried to use a life leech skorn, because it's kinda expensive (probally will worth more than this entire gear!), but if you can afford it, go for it. cant be wrong.
- rings/ammy
ah, the jewelry. for every build/char that i build, i always let the rings to be the 'swap' options, because, as you can see, you cant get rid from helm/chest/belt/boots/gloves, and basically there's no much option for 'budget' shoulders/pants/bracers. rings always can be easily swapped to get more surv or more damage, if needed.
well, at this point, if you are with 30k life full gemmed with strenght, and with ruby @ your helm, you just dont need more life at all for alkaiser runs. worry to get 45-50k ish if you are planning to do ubbers @ mp8+
in order of stats that really pump your dps, i can say:
%elitedmg > critchance > critdamage > avg dmg (xx-xx) > strenght. AVOID ASI atm, too expansive, and not so much usefull for us.
example: unity
http://us.battle.net/d3/en/item/unity -> thats a pure example of a good piece of jewelry for us.
that type of jewelry will raise your dps to heavens.
another option is a cold soj with rend. any elite will be melted if you use the unity+soj combo

ok, now that you are ready to smash some heads, lets talk about the skill
passive:
- weapon master (10% cc, no brainer)
- ruthless (5% cc / 50% cd)
the third choice depends. if you are doin alkaisers or playing @ low mp levels, you will notice a lack of fury. lack of fury = lower dps. then up unforgiven, since there's no reason to go defensive.
if you are goin to higher mp, you will notice that, no matter what build you use, you fury will be ok. then go for bloodthirst for the extra 3% LL.
if you have a LL skorn, get superstiction (-20% non-phys dmg) or tough as nail (more armor).
skills (the alkaiser speed run build)
- sprint w/ run like the wind
your 'white monster's smasher'. spam this shit and just leave the white mobs behind. with ticks between 40-60k crit, EVERYONE AND EVERYTHING WILL DIE. keep moving!
- whirlwind w/ hurricane
was goin to get struck? shitton of mobs ahead? elite? just go as a classic double nado ww and brush all the shit away, and keep moving!
- marauder rage w/ into the fray
mandatory. needed to keep your rage topped. keeeeep mooooving!
- rend w/ lacerate
- leap w/ call of arreat
- ground stomp w/ wrecking smash
here is why this build SHINES to farm alkaiser!
when you are running mad, like a double nado does, leaving tornados and ww the shit away, a elite appears far far far far away
wat you do?
LEAP INTO THEM - they will become stacked due to call of arreat rune (18yards effect)
GROUND STOMP THEM - 1 mob away from the stack? plz come here (24yards effect) and get STUNNED 3 SECONDS, BITCH
REND THEM - they will receive 900% dmg over few seconds. with soj, THEY MELT IN 2-3 SECONDS
KEEP MOVING!
@ alkaiser classic run, mp0, i can do 70million xp per hour!

skills (the hota build - for higher mp/ubbers)
haha, that build is funny. nevah see 2milions crits before?

lets go
- marauder w/ into the fray remains, its mandatory here as well.
- rend w/ bloodthirst, to keep you alive while banging the idiots (extra life leech)
- WOTB w/ insanity, as a OFFENSIVE COOLDOWN (or thrive on chaos - you can keep it like any double nado barb does due to 5ik set bonus :D)
- war cray w/ impunity, extra surv, mandatory for any barb
- overpower w/ "that reflect 35% dmg rune", as a DEFENSIVE COOLDOWN (dude thats godly, -35% all dmg, works like a panic button!)
- hota w/ smash. your main attack. 1-2mil crits. low life? BANG AND YOU JUVED!
this build works fine versus few mobs. sucks versus the mobility of double nado build, but wins by far, if we are talking about surv and dps w/ 2h

just aggro the shit to you, rend everyone, SMASHSMASHSMASHSMASHSMASHSMASH rend SMASHSMASHSMASHSMASHSMASHSMASHSMASH, end
if you are getting fury issues, swap overpower for bash w/ instigation, then just 2-3 bashes and you are with full fury
hope it helped, and sorry for my engrish!
