Solo Nezarec with Whisper of the Worm

The balancing of this game never fails to surprise me, how is this weapon which is super akward to use and super unforgiving worse than every other mediocre precision fusion rifles, it makes no sense. Even fafnir does more than this thing. Even if it had infinite ammo like when it released, it would still be mediocre, but at least it would be a cool weapon
