The rest of the sentence is key. "there's no reason to kill one over the other"

IE your not camping Naul for the rare "naul tooth necklace" a ilvl 90 neck with meld slots (tried to think of a way for it to be "B" grade loot and still be worth camping.. but the point is there.. a item that is worth camping that is somehow superior to just running Brayflox a couple times and buying a ilvl neck off the merchant)

Your just killing "any hunt mark"
