Exactly my thought process. Weapons are all well and good, and even better when you get them, but to have an exotic raid piece drop would be something extra to work for. Once you've got Crux and potentially Hunger and/or Black Hammer, theres not much else worth raiding Crota for, just my opinion. The raid primaries are so underwhelming, aside from the vaguely new/interesting perks they introduce, albiet restricted to one enemy type in most cases.
