Sad to see this feature ending, the WoW jokes were funny, and I'd like to see it go all the way until level 85.
That said, I think the point of the Fulbrows dying was that they owned the land the Defias were operating on. I'm not sure, but I think the sequence of events is that someone did the chain of quests for them, helped their situation, and then when they left they were murdered right before the new generation of adventurers shows up.
That said, I'm surprised you didn't say anything about the most (in)famous aspect of Westfall. The bit where you head down to the farm where you get the harvest reaper quest, target a chicken, and then do /chicken 100x or so. This causes the chicken to eventually give you a quest to get it some feed. You go over to the farmer and buy the feed (which is why he sells this otherwise uselss item), do /chicken again and feed the chicken, at which point it leaves behind an egg you can collect to obtain a white chicken as a static pet (not to be confused with the black chicken pet which you buy). This is still active post-Cataclysm apparently.
I mean honestly, no commentary on Westfall, especially a humerous one, is complete without mentioning adventurers clucking at chickens for that easter egg.
