Disclaimer: 12 hours in, so I'm by no means an expert on Skyrim. Might be harder later on, for example. IDK.So far I like it. It definitely seems to be a trade off... you take more damage, but you do more damage too.My take, with what I know and have experienced so far:Taking more damage can be mitigated by the crafting professions easily, at least in vanilla Skyrim. Pretty self explanatory, just craft good armor, throw some nice enchantments on it, gulp some good potions even. More than makes up for the armor loss from no shield IMO.Dishing out more damage: here is where dual wield really shines, I'd say. Dual Flurry and Dual Savagery combined with Armsman makes for some really nice +dmg overall. And then you have the weapon specific perks, Hack and Slash for war axes, Bone Breaker for maces, and Bladesman for swords. My personal take on those 3 is that Bone Breaker is the best by a mile. 75% ignore armor is pretty insane combined with the above perks.EDIT: in terms of aesthetics and gameplay, I guess it is personal preference. I like to bash faces in with dual wield more than sword + shield gameplay, and I like the animation better.
