Man, if you don`t have lifeleech why don`t u take the fattest 2 handed mace you`ve got and play berserker? Also wtf is it with your dexterity rating and battle orders and the level in Bash?
Just check the sticky for some guides or search for Nightfishs untwinked Berserker guide in the single player forums. At least it helped me playing a remotely satisfying Barbarian, when I didn`t have any gear.
And why would you take Whirlwind as secondary attack? Both DS and WW deal physical damage so that makes NO sense at all. The only secondary attack you should consider is Berserk. Why? Cuz it lets u deal with physical immunes in hell quick and dirty.
I tell you what I did:
Read Nightfishs Zerker guide. Used his build. Realized I had enough wealth to get an Immortal King Set. Read Immortal King Barbarian guide. Never looked back.
Edit: If you play on Europe HC I can help you out with a Steeldriver or Bonesnap. Got 1 or 2 left and I`d give em away for free.
^^ Ignore above two advice and that in the other thread. They did not read the fact that you want to make a WW/DS barb and not frenzy, berserk, etc. etc.
I am currently making a barb planning to use the item set Bul-Kathos children. WW/DS is the best skills for such a build as well as they are the most awesome/ most intuitive skills a barb has. He is only level 20 atm, but my planned skillbuild is
20 bash ( DS synergy and a strong attack early game )
20 sword mastery
20 battle orders
1 double swing
all prereqs and 1 point wonders
The main point about the double swing is that it can very easily deal with manaburners ( the bane of WW ) and as a single target spell/your main attack throughout early levels of the game.
Also this is THE build for an untwinked Barb. Don't let anyone tell you otherwise - you can see in this thread what happened to a poor guy who tried doing an untwinked 'berzerker' ie a build that heavily relies on two level 30 skills and synergies. All Barb builds are heavily gear dependent, however this one is the least gear dependent and DS/bash being available at very early levels make normal and nightmare a breeze.
As for weapons, I highly suggest getting swords. This is because you can wield both 2H and 1H swords, thus doubling your amount of choice in items. I currently have the death's set+shadowfang. Other good stuff are coldsteel eye, bloodletter, clegaws set.
Your skillbuild is wrong but not that far wrong. Remove all points but one from iron skin ( that is a 1 pt wonder ), and put them in battle orders. Also, I don't think 9 pts in DS are necessary.- it doesn't have to be completely mana free after all and 1+ skills are just fine. Put those points into whirlwind, since you are making a WW barb after all. Infact you should max out WW and put fewer points in bash at this stage.
Edit: Also for PIs, what you want is lawbringer runeword or reapers on merc. Don't waste time with Berserk, one point is okay if you can't get the above.
