I agree NNI isn't that hard at all with the right people, but finding people good enough for it can be hard whereas anyone can do salvage (killed arrapago boss with a terribly geared whm and perle bst!). I've got the pieces I need from NNI, so any more is just a bonus in that respect. But yea I agree salvage takes longer and sometimes the rewards don't fit in with a certain set, and to get that set can be harder in its own right than just spamming NNI. But they aren't 100% useless at least.
