Maybe it was helping Tirion in the Plaguelands; maybe it was helping Mankrik find his wife. Everyone had a favorite NPC in the old world long before any of the Cataclysm changes took place. But now that Azeroth has been shattered and reformed, we have seen not only new faces but old favorites in new and strange ways. Questing recently (if you haven't taken the time to, you should!) has been a strange mixture of familiarity combined with entertaining surprises from characters we've never met before.
Our guild has been abuzz with people having long discussions over who is the best, as most of us have been rolling up new low-level alts to poke, prod, and explore, or even just taking our mains out to do more Loremaster achievements. Some people love various quirky characters (or outright hate them), and other people like the more serious lore figures. All in all, we've had a lot to talk about regarding the people in the new Old World.
If you've been out and about doing the new quests, who are your favorite new NPCs? Is it Zen'kiki in Western Plaguelands? Or Lunk from Searing Gorge and his adorable pacifism?
