I say nay. Whisper is dope but if you miss 1 shot or your target goes immune before your 3rd your screwed. Darci shreds in every phase battle. The ones where you only dps for a few seconds or to a certain threshold. It holds like 7 in the Mag and high 20s for reserves and picks up 8 shots a brick without any scavengers or reserves perks. With the catalyst you can pop off 7 box breathing heavy ammo tier damage shots as fast as you can pull the trigger. In a Luna faction rift it's second to none. None. Again whisper is great but not the slightest bit forgiving against an agile target or phase mechanics. If you Nerf it to special it'll literally be a wasted exotic slot equivalent to every other sniper in the game that rolls box breathing. As far as crucible goes. It doesn't matter what you do to it. If you're using whisper or Darci in pvp you're doing it wrong. This thing melts in gambit prime, trust. Leave it heavy. It's a monster. All these people hating just haven't used it effectively and think the whisper is the only good dps sniper. You want to know what taking a weapon from heavy and putting it in special does? Ask merciless. It went from king dps to less than nothing(though I use it in pvp for fun because of the catalyst range and tight grouping, erentil destroys it in every category, rip)
