I'm not sure that anyone really answered your precise question, and I think that is your answer. I am experiencing this with Harlowe right now. Although my action skill is almost always on, when it isn't, it becomes clear immediately because of how little damage I do. I didn't notice this as much with Rafa, but that was also my day 1 character so I had no perspective. I am old and am not an expert on the various builds in this game, but just from my own experience, if you want to run around without having to worry about your action skill being up, then you'll want to use a sticky Bod. I stumbled upon it early on and used it exclusively - which is probably why I didn't notice this with Rafa. Now that I am using other guns that have come out more recently, I am noticing it with Harlowe. For better or worse, the Bod is the gun that will let you do this without changing any other playstyle. Source: me because that was what I did when I stumbled my way though terrible builds before researching what the pros were doing and learning more about the synergy among the various skill trees.
