I've played the new Garden raid, and the strikes, and I gotta say, I don't see why Whisper needed a nerf. Heavy ammo is scarce (even with heavy ammo finder perks), and I think a perk that provides infinite ammo as long as three consecutive precision shots are hit, is more than deserving of my exotic slot. So please, bring back the Whisper that provided infinite ammo, or move it into the energy slot, making it a legendary. Please.
It'd be fine as is if moved to a special weapon like the spindle and hammer we're in d1. Ammo isn't exactly everywhere but its common enough to have enough to warrant using it on dps phases.
