Hawkmoon used to 1-shot. Got nerfed to only 2-shot at best. Never seen in Crucible again. The Last Word was glitched, and players would exploit it to get 2-shot kills at crazy ranges. Got fixed to no longer get glitch damage bonus and have less range. Still heavily used in Crucible (overused?). Thorn was underwhelming at first, then Bungie improved it. 2-shots and the user ran away, leaving victims to burn out. Overused to the point of becoming the most hated year 1 weapon. Nerfed to 3-shot status. Making a resurgence in Crucible. Still a hated gun (for obvious reasons).
