IDK how yours is set up. It took me a hot minute to actually sort how to build around the weapon back when I routinely used it. You need the improvements unlocked. Use the 4rd light burst for PVE. Must have the Vorpal Weapon applied. Apply Armor Piercing rounds in the mag. That will grant a 25% DPS increase to barrier champ's shields. Alt Fire 1 taps shields. Hit crits and you can kill most of them with one full set of targeting data. If you want to take to another level, run 2 Kinetic Surge mods for an additional 17% DPS boost. Run Shield Break Charge in the Arms to trigger the surges easily. Now you're up 37% with your DPS. Pair the Tech Sec set with just 2 pieces for an additional 200% bonus. All in all it's a 237% bonus. If you're really mathing here and want to shift focus for a split second just to further stack numbers, Arby would be a beast with this setup, as the intrinsic Disruption Break would apply another 50% kinetic debuff to the target. IK that's not RZ, but just a fun addition to explore mathematically. It's not complicated. Most people just remain ignorant of the in game numbers. If you can't make use of it, idk what to tell you other than "skill issue". https://www.twitch.tv/videos/2405395247
