If you equip a shield you lose the 2nd attack, effectively giving you half the damage you have without a shield.
So technically we already have duel wield in the sense of 2 attacks, we just cant equip an actual 2nd weapon in the off hand.
I would like to see a dagger in each hand though but that is just a cosmetic tbh.
Two daggers would also give a fair amount of +stats which may imbalance the class.
