Whisper needed infinite ammo removed but I agree that white nail needs something added to make it worth while like maybe a rapid it type addition? Super gen. Exotics could have had perks tweaked to add more nuance like direskull changed so that each kill with a nova gives a player a stack buff where each kill consumes 1 stack and gives a chunk od super energy. So it CAN reliably allow multiple supers but requires more than using your Super. Apply similar changes to other exotics everybody happy.
