You pretty much need Grapple Grenade to traverse some of the jumps in the content, too, especially if you're a Hunter as you get almost no height with a single jump. I had to jump multiple times just to get enough height to clear what is normally clearable in one, and woe be unto you if you overshoot your landing -- you'll feel like a Warlock who slowly drifts to an inevitable death. The modifier is supposed to come with the Grapple Grenade modifier for a reason. But guess which modifier they took out because it was letting people complete content "too fast"? Yup.
