Suspi's NCE experience was much the same as what you describe, and I haven't been offended by anyone else's comments. She was involved some with the werebear AMPC and momentarily in a couple of other little bits, but because of her ECL handicap I became a little too driven trying to get her off second level, rushing around doing deliveries until she accumulated about as much gold in a week as Iridni achieves in months.
If your offense is at something I said, my point is only that a strategy of soloing deliveries is always available, NCE or no. Since NCE is a rare thing, I (personally) would rather be involved in some of the unique experiences afforded during the uncommon occasion.
I agree that fetch quests don't have to have any effect on other players, and I take no issue with anyone who wants to spend her NCE doing them.
