That's what I did, but I still found that spamming the scimitar was always better than alternating between two weapons. I suppose I should just check youtube for videos of how to properly use duel wielding.
I think the problem is that the game set you up for failure wrt dual wielding.
Let's break it down.
First, there is no explanation or tutorial for "Power Stance." Power Stance requires 2 weapons of the same type i.e. Curved Swords, or Straight Swords and you might have 1.5x the STR and DEX required to wield these weapons. Then you must hold the triangle button down and your character will raise the weapons up a bit to confirm you are now in this stance. I think everyone in this thread now knows this, as its been asked and explained multiple times, but there is nothing in the game to point you to this.
Second, The starting class that defaults to dual wielding is weak. As has also been covered in this thread, Swordsman starts with 4 VIT and 4 VIG. (But 7 INT and 5 FAITH ?? )
Third, The swordsman weapons are not even compatible with power stance. While they each come at +1, one is curved and one is straight, so if you wanted to keep them around, you'd never stumble into power stance.
All of this said, I have really enjoyed dual wielding in the mid-game. I'm level 66 and have been dual wielding falchions in power stance for the past 2 game sessions. The improved moveset in powerstance is very fun, but does require some exploration to find the combos that you like.
I think true dual wielding is a great addition to the game, but its odd that they made the discovery of how to do it successfully so hard considering how much better the game explains almost everything else. (Improved menus and tooltips.)
