It was stripped away because it did exactly what it wasn't supposed to do. The same reason Thorn wasn't brought to Year 2 is the same reason Hawkmoon's range was nerfed. Hand Cannons were designed for close-mid range encounters, and Bungie has confirmed this is their intention! Hawkmoon was able to challenge not only snipers but the only winning point of Scout Rifles as well. It's nerf was taken away for a very good reason. It's fine as it is now. I don't want another Thorn. The Hawkmoon rewards a skilled hand.
