No Land Beyond and Necrochasm are both terrible exotics, but the crown goes to Necrochasm because of all the effort and grinding involved in getting it only for it to be massively disappointing.
High RoF, non-existent impact, laughably low range? Thanks Bungie.

The main grind is the Husk part, and at least you can combine that with Glimmer/engram farming on "we've woken the hive". After that bounties can be used and you don't need to actually use Alley at all.
