Melee focused meme config taking advantage of [Rakta Dark Dagger]'s shield restorative effects to keep her charged up. Keep [Balefire Charger], Gloom, and Haven up at all times and spam pillage and melee attacks to delete your opponents.
The [Balefire Charger]'s job is to delete nullifier bubbles when they appear. Gloom provides CC and healing for the squad. Haven hits enemies with radiation, allowing you to consistently trigger the [Rakta Dark Dagger]'s shield restore on radiation procs and keep your shields charged. [Blazing Pillage] will armor strip and give easy overshields.
Have fun...
