There will realistically always be a non-samurai in the party that will give a slashing debuff so honestly I wouldn't call it utility, it just so happens one of its required Sen combos also happens to have a slashing debuff.
Other classes benefit from it, 2 of which you will always have (tanks). I'd call that utility. It isn't much, but it is a thing.
