Dwarf: Excellent work my elf friend, but the news is ill. Our spies say that Larry, Curly and Moe have doubled their efforts to bolster the orc forces. Return and thin their forces! Defeat 5 siege masters and 5 berserkers and deal a demoralizing blow!
Me: I told you Larry, Curly and Moe are tough. I've fought them twice now, don't you think I should deal with them? Or maybe go straight to the top and take care of Bob - I've fought him twice as well and I can take him.
Dwarf: Such an errand would be folly elf! Thin their forces and they will be driven back!
The sad part is that five followups to the same camp from the same questgiver is an exaggeration, but three is pretty common. Sometimes there's another questgiver with quests in the same camp who might send you back a fourth time if you didn't juggle the two sets of quests in precisely the correct order.
It reminds me of the quest in Evendim where a hobbit says he simply does not believe that there are no boars to eat in the zone. Players need to spend at least 30 minutes supposedly looking for boars (you can do whatever you want with the time) to convince him that there are, in fact, no boars in Evendim. What does Turbine do to follow up on this satirical take on their own quest design? Send you to kill 10 bears instead.
