I main a hunter and was primarily a gunslinger throughout Y1. No. This doesn't need to be. A precision hit with the knife already does great damage. It leaves a full health guardian very weak, a couple bullets would finish them off. Add the incendiary blade and it does even more damage, albeit over time. Most OP build around the throwing knife already wrecks if you can land the throws. Sealed grasps. Monte Carlo. Couple shots from Monte, throwing knife. Rinse & Repeat.
