The Necrochasm wasn't really all I was expecting, being such a hard task and a very lucky person to even get the evolution material to get the notorious Necrochasm, it did not meet my expectations. The gun is very weak, not much a step up from the Ally. Then after the Nerf it made matters worse. Still being decent in crucible, the Necrochasm seemed intended for PVE. But after the patch it made the gun even more futile. Buff?
