I did most of the quests there, trying to collect names of the broken ones. Here's what I got so far:
[Kickin' Nass and Takin' Manes]
-couldn't find the baddies where they were supposed to be, according to wowhead
[Gluttonous Lurkers]
-you feed the basilisks 5 times to make them give you the quest item... but the food aggros and they don't change form when they eat 5 times.
[The Storm King's Vengeance]
-i think this quest is supposed to be like the DK dragon quest; you get on the giant and kill a bunch of bad guys... problems is, when you accept the quest, it doesnt put you on the giant like it should. It's possible to do the quest without him, but killing 100 baddies and a few elites would take a really long time.
-this quest is in the middle of a series
If I get back to the area to do the rest, and find more bugs... I'll edit this and bump the thread.
