We are definitely aware of the feedback coming in about the Necrochasm. No, you're not using it wrong. :) The weapon is performing as designed. Fictionally I love the weapon, and as an exotic gun I believe it definitely achieved our goal of being a unique item unlike anything else in the game. However, I do agree that competitively it is not as strong as Mythoclast or other highly used Auto Rifles. The acquisition of this weapon was also significantly more involved than other exotics. We did a huge pass on exotic weapons shortly after Destiny released, and will likely do more updates like this in the future. Community feedback is taken into heavy consideration when we make these updates, so I'm sure we'll be looking closely at Necrochasm when that time comes. Until then, thanks for letting us know how you feel and keep it coming.
