Bungie is entirely unaware of how to properly balance weapons, so whenever something exceeds the intended utility, they nerf it to hell. Happens with a lot of devs. FromSoft on day one nerfed the Fume UltraGreatsword into the friggin' ground because people complained a gigantic wall of a sword did "too much damage". They never fixed it, so it's outclassed by pretty much everything in its class. Yay
