Apologies again for the misconception. Please see the last post, specifically number 4.
Thank you for the evidence though!

Actually dual wielding also existed. It wasn't common, but it happened. In Europe, it was normal to use a sword accompanied by a parrying dagger, for example.
Also literally everything I said about wizards still stands. Dual wielding happened in real life; you can't complain about that being unrealistic and keep wizards.
And furthermore, D&D is as vanilla high fantasy as it gets. It's perfectly normal for fighters to use outlandish weapons and exotic fighting techniques.

Here are a pair of HEMA experts talking about historical dual wielding in Europe.
