My personal reason is because I enjoy quest like that more then the ones like Here lies the abyss or in hushed whispers because I actually feel sorry for all parties involed in the bloody baron questline, but in quest like Champions of the just and In your heart shall burn I just simply do not care about whats happening to the people in those quest because they don't give me a reason to.
Different strokes then. I enjoyed In Hushed Whispers, for example, because I care about the DA world, and I had a connection with the companions I'd taken with me on that quest. I enjoy that DA gives me the opportunity to forge my own relationships with various characters, I'm not forced into friendships with people I don't want to be bothered with. I struggled to care in TW because the vast majority of my relationships had been decided for me, something I generally don't like. Also because I didn't find the majority of the characters to be terribly likeable, I struggled to find motivation to save them or help them. With the exception of rock trolls, who I will always help because they are awesome.
The Baron stuff was good, but I can't really say I sympathised with him or his wife at the end. The daughters though, yes.
