I don't think I would want to have the Power Slash effect on every combo whereas I don't mind the Soul Eater one on every combo so going to disagree here.

Before the changes to remove the Power Slash combo I personally only ever used Power Slash combined with Dark Arts to establish some serious threat on a Boss. Most the time used the Soul Eater combo since it provided better gains. Power Slash did provide more of an impact than Soul Eater with the big thud sound but since I used Soul Eater combo majority of the time I kind of don't mind the change.
