The raw is bad. Sticking with a bad design so the passive is never used or always feels worse to use than other?
RAW, it's undoubtedly weak. However, this particular "fix" throws of the balance with the other abilities, being disproportionately better on a paladin (and rogue multiclass - I'm sure someone will find a way to patch that in eventually).
RAW, the main benefit is it is multiplied on critical hits, unlike Dueling. This makes it useful for crit fishing builds, such as the Champion, should it ever make it in. Of course, the champion is also rubbish by RAW, so your mileage may vary...
