Maybe we should stop believing that dual wielding can be done without a good portion of strength and that there is a massive difference between a dex-based DW and a str-based DW character.
I remember watching a documentary about various weapons and the amount of strength needed to wield them properly. Turned out that even a single rapier in your (strong) main hand would be quite heavy and required lots of strength, so it would be easier for an average fighter to simply use a two handed weapon.
Now if you used something in your other hand as well, this would require far more coordination, strength and training. Especially if the off hand weapon is more than just a dagger.
