The entire point of that quest line is to prove you're not an impatient dick of a hero and are willing to help people even in the most simply of tasks, like a real hero would do, helping people in any way possible.

Other "go get this" quests yeah they're annoying but game developers need to make the game longer than it is somehow or people reach end game faster and are bored as crap. If I got to end game about a week earlier than I did I'd have canceled my subscription until 2.1 came out. Sucks but is necessary.
