I don't see the problem if quest chaining it's made good.
WoW in years got better with quests, and with cataclysm did a great job chaining quest with a real story (not counting the entire indiana jones trilogy...). If they manage to write quests like star onion brigade, i'm up with it.
also, i don't find anything spectacular in leves story-wise, rokien. They have the lamest story ever, if people actually read them :|
