The best quests are the ones already completed and forgotten about in the journal, the ones we got XP for and no longer have to do because it's bland and boring.

Joking aside (or was I) we'll have some quests that have Lore tidbits in them and we'll have those boring quests which are nothing but kill a certain amount of mobs then return an item to the NPC. Then of course after the exclamation point is gone, we'll forget all about that NPC. Nothing wrong with free xp every now and again, but I'd hope for those to be the minority and not the majority, just a little dash of salt can sometimes help the bland flavoring, just a little challenge sometimes is all I ask for.
