sifus.. i am a new barb... may i ask if is better to wield 2 weapons or one weapon with a shield? and does axe, sword and mighty weapon have any difference?
for early game, or unfunded..go for dual wield...because in order to use 2h weapon effectively, you need to have to high damage output so you could life steal more for hp regeneration because the amount of life u gain is dependant on your output dmg. As for dual wield, you have the chance to roll life on hit on each weapon as life on hit is not dependant on your dmg output, which means you still leech the amount of life even if you have crappy dmg.
life leech is an important element for survivalbility for late games in inferno higher MP.
as for your 2nd question,
there is a passive skill for barb which is called Weapon Mastery. the benefits of this skill depends on the weapon you use on your mainhand(left weapon as displayed in game) which is as follows:
Axe/Mace : 10% critical chance
mighty weapon: fury regeneration per hit
as for dagger/sword/spear...i dont think these benefits(% dmg increase / atk speed increase) are good....
most of the barb plays wind whirl tornado...so mostly uses either axe/mace/mighty weapon dependant on the situation...some barbs has weak fury regen, thus they will use mighty weapon ..while on the other hand some has decent fury regen and prefer higher dmg, thus they will go for axe/mace for the extra dps boost form 10% crit chance.
for further info about whirlwind tornado build, you can try youtube about it...for the mechanism on how it works...i tink other people in this thread can explain as if i continue to explain...it will flood this whole page...=X
hope this clarifies your doubts.
