I assume that It's somewhat easy to get Husk of the Pit (kill a boss at the beginning of the raid on any difficulty, or after you beat the missions, something along the lines of that, or maybe as soon as you buy it and do the first mission, kinda like how you got the first auto rifle), but getting to Necrochasm has you doing something quite hard like beating Crota on Hard. If so, two things:
1: You've finally figured out how to make a way to get a exotic that isn't pure RNG, and it requires you to do a good amount of work.
2: You have a template on for making other raid exotics (or even all exotics, hell, maybe if you could think of something, raid weapons and even armor, although getting that [http://www.bungie.net/en/Forum/Post/73744279]Raid Vendor[ would work just fine) in future raids, or even the Vex for VoG obtainable by everyone, not just people who get lucky.
This is great. You guys are showing progress. Keep it up!
