I agree. There are a number of quests that I DID complete, then - because I am so anal about completing all quests - when I screwed up and out-levelled one, I restarted only to find that some of the quests I DID complete are no longer available. Grrrr. Bring 'em back. One-offs area pain in the bum and are not fair on new players who never even had a CHANCE to try them.
