Going off of Detective's issues, I think I might have the simplest suggestion:

Cap bonus momentum from crits (Not refunded momentum, soul rage, etc) at +2 per turn. A duelist gets it on one crit, while other classes can still attain it by critting with both weapons.

Still allows Fleur to be good at letting a duelist be a duelist without making duelist overly appealing for Fleur alone, if anyone with two weapons can theoretically attain it, while making it easiest for Duelist to continue using it in the face of enough critical evade to make double crits unlikely.
