Necrochasm is by far the worst exotic in the destiny game. The fact that it takes a long time to aquire the gun: get Husk of the Pit (it rarely randomly drops), then griding to get to rank 4 with eris to upgrade for a better weapon, but still weak, then have specific unbelievable instructions to get the crux of Crota, only for it to still be a piece of crap. It's not unusable, but as an exotic, it should of been better. Give it more damage, OR increase the mag and give it explosive rounds.
