I remember that by the time it got nerfed I was thinking that it was kinda justifiable because the damage resistance was crazy high, nowadays we call it resilience and it works for every subclass in the game without any setup and with more setup can even surpass the original Renewal Grasps.

Honestly I would prefer a rework at this point, since damage resistance exotics now is just whatever, it's better to use exotics that enhance survivability with healing (Loreley for example) or other kind of protection (like invisibility with Omnioculus) instead of using exotics that just adds even more resistance.

The only possible rework I can think is giving another charge of grenade (with normal cooldown) and making it more lethal without the grenade aspect (like weakening the slow to add a possibility of escaping the grenade but enhancing the damage inside the duskfield radius that can actually kill enemies instead of doing minimal damage)
