I do, they're fantastic! Nothing out DPS's a full auto shotgun with field scout, 2800 damage per shell, three shells a second, you can out DPS a Gjallarhorn! I have a full auto Judgment with void damage and a 7 round mag, it eats Praetorians, 2 seconds max. Invective is great too! Just make sure your shotgun is full-auto, its vital to your DPS.
