I love it when Blizzard gives you a choice to do something distasteful or choose a "nicer" option. It gives some room to react as your character would. I hit another quest like this on my undead hunter where she was given a choice of pulling people out of the ground or bashing their heads in.

I appreciated the quest in Hyjal where you could either choose to kill the harpy or show her mercy, but I feel like these quests are a minority in WoW, and it disappoints me that there's little choice about your character's path. Sure, you can decide not to do a particular quest, but that was a lot easier in Vanilla when not everything was a chain. Don't get me wrong, I like the flow of the new streamlined quest design, but it's frustrating that you often can't progress in the game without doing every quest.

This is particularly true in the Cataclysm zones; it's not like you need every scrap of XP to level, but in many cases you won't have access to certain reputation vendors or daily quests that are pretty crucial in the endgame unless you complete every story quest.
