Its just as subjective to say if the quest is there people will do it. The point is the quest is not a challenge. Its a block. A person with no skill can complete it but its a time sink and, in my opinon, one that is not needed. Like some have mentioned if the quest are not manditory but help lead up the raid that would be cool but putting something in your way that just takes more time, not more skill, doesnt help anyone.
