You guys are arguing about realism in a setting with magic. *That* is childish.
Here's the reason why dual-wielding would be a horrible idea for Divinity Original Sin: Str/Dex hybrid viability. Or, to explain it in more detail...
First, let's look at D:OS without dual-wielding. Rogues, assuming they are properly designed/balanced, would not have anything to put in their off hand. As such, daggers would and should be balanced around the assumption that there is no off-hand, and thus be roughly as powerful as a two-hander. This makes the concept of a Str/Dex melee hybrid appealing, since it could essentially allow you to run a "two-hander" along with a shield, simultaneously; this, plus the Man-at-arms skills, is a fair tradeoff for the Con, Speed, etc. you'll be missing out on by pumping Str.
Now let's imagine D:OS with dual-wielding. Rogues would now be dual-wielding daggers, which means Rogues would have to be balanced around this. This would mean that a single dagger in the hand would no longer have approximate two-hander power. This, in turn, would mean that Str/Dex hybrids have less to offer players, because there's nothing special about actually getting to use that off hand slot anymore.
There is absolutely nothing in that argument which deals with realism (or lack thereof). This isn't about realism, it's about game design.
