I have tried it few times before, but never liked it. This time, my level 30-ish Orc mace and shielder had a couple perks to spare, so I put them into the speed up attacks with dual wielding slot (I forget what they are called) and now he absolutely destroys. I can't even go back to using a shield because of how effective my dual Orcish war axes are, and I haven't even put the perk into increasing the power of dual power attacks yet.
What do you guys think about dual wielding?
